Available in PDF, EPUB and Kindle. Book excerpt: In the past 10 years, perovskite solar cells (PSCs) have drawn great attention in both academic and industrial sectors. Over 25.5% power conversion efficiency (PCE) has been reported from PSCs by three-dimensional (3D) methylammonium lead iodide (CH3NH3PbI3 or MAPbI3). However, the previous studies have indicated that PSCs exhibited poor stability. Thus, to commercialize PSCs, the development of efficient and stable PSCs is required. In this study, we reported two approaches to develop efficient and stable PSCs. One was to develop novel all-inorganic perovskites, where Pb2+ was partially heterovalently substituted Nd3+. Another was to develop PSCs with a bulk heterojunction (BHJ) device structure. In the first approach, it was found that the CsPbI2Br:xNd3+ thin films possess enhanced charge carrier mobilities, superior crystallinity, and enlarged crystal sizes, but with enlarged optical bandgaps. As a result, PSCs by the CsPbI2Br:xNd3+ thin films exhibit more than 20% enhanced PCEs and boosted stability compared to those by pristine CsPbI2Br thin film. To further boost the device performance of PSCs, solution-processed 4-lithium styrenesulfonic acid/styrene copolymer (LiSPS) is utilized as the passivation layer. PSCs by the CsPbI2Br:xNd3+/LiSPS bilayer thin film possesses reduced charge extraction lifetime and suppressed charge carrier recombination, resulting in 17.05% PCE and dramatically boosted stability compared to that without the LiSPS passivation layer. All these results indicate that we develop a facile way to approach high-performance PSCs by all-inorganic perovskite materials. In the second approach, we found that all-inorganic perovskite incorporated with low bandgap conjugated polymers, forming BHJ composite thin film possesses balanced and enhanced charge mobilities, superior film morphology with enlarged crystal sizes, and suppressed trap density As a result, BHJ PSCs exhibited a 21.08% PCEs, which is more than 16% enhancement compared to that without incorporated with low bandgap conjugated polymers. Moreover, BHJ PSCs possess suppressed photocurrent hysteresis and enhanced device stability. All these results demonstrate that the development of BHJ PSCs is one of the facil ways to approach high-performance PSCs.

Available in PDF, EPUB and Kindle. Book excerpt: Perovskite (CH3NH3PbI3 based materials) hybrid solar cell has been one of the most promising photovoltaic device due its plenty of advantages such as low price of raw materials, easy fabricating procedure and relative high power converted efficiency (PCE) (compared to polymer solar cells) and so on. However, the still not very high efficiency of perovskite hybrid solar cells makes it at a disadvantage position in the competition with traditional silicon solar cells. Thus, to make it more competitive, efficiency enhancement comes to a vital issued need to be addressed. There are three chapters in this thesis. In chapter 1, a general introduction of perovskite hybrid solar cells including working mechanism and development is giving. In chapter 2, we use the electrochemical material PSBEDOT to function as the hole transfer layer to observe the high performance of perovskite devices. In chapter 3, to improve the efficiency of perovskite hybrid solar cells, we have blended commercial available Fe3O4 nanoparticles in to the active layer of perovskite hybrid solar cells to see any performance improvement. To further enhance the device performance, some magnetic treatments have been done in the perovskite layer of the device including the involving of magnetic nanoparticles and external magnetic field. Finally, we have got a result with PCE reaching 14.40% with a dramatically enhanced short current density.

This book was released on 2017 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a promising renewable energy technology, perovskite solar cells (PVSCs) have made a tremendous progress and received significant attention in recent years, due to the low-cost solution process fabrication, superior charge carrier transporting ability, and decent device performance. In this dissertation, the device performance of PVSCs is enhanced through integrated approaches, such like perovskite thin-film morphology engineering, interface modification of the contact between perovskite and fullerene derivatives layers, and new device architectures. Chapter 1 and 2 briefly overview the current status and the operation mechanism of PVSCs. Chapter 3 demonstrates the importance of the perovskite morphology to the PVSCs performance and the approach of fabricating homogeneous perovskite film. By incorporating Cl- anions, the morphology for both pure I and mixed I-Br perovskite become continuous, resulting in an improved device performance. In chapter 4, another methodology to manipulate the perovskite morphology and crystallinity is proposed. An additive, DIO (1, 8-Diiodooctane), was carefully chosen to manipulate the perovskite morphology due to its capability to chelate Pb2+ cations. As a result, the increase of precursor solubility and the change of the perovskite crystal growth path generate high-quality perovskite film and decent device performance. Chapter 5 presents an interface charge redistribution between the perovskite active layer and fullerene derivatives, like C60, PCBM, and ICBA. This interesting finding gives us a deeper understating when we try to choose a suitable charge transporting material for high-performance PVSCs. In chapter 6, a device fabrication process is employed to enhance the charge collection efficiency for fullerene layer and passivate the defect states at low bandgap perovskite surface and boundary.

Available in PDF, EPUB and Kindle. Book excerpt: Unlike silicon, solution-processable solar materials are flexible, lightweight, easily processed at low temperatures, and display a wide variety of colors and degrees of transparency. These attributes open new opportunities to integrate solar power creatively and inexpensively into new markets such as electric vehicles and multifunctional architecture, as well as augment the performance of current solar technology in tandem cell configurations. One of the central challenges to realizing this vision is the high degree of disorder generally exhibited by solution-processed materials, which provides an abundance of trap sites that limit carrier transport. Hence, the performance of many solution-processed materials is governed by a trade-off between light harvesting and carrier collection, where complete absorption of sunlight requires active layer thicknesses greater than the diffusion lengths of the performance-limiting charge carrier. Overcoming this compromise requires either modifying the optical and electronic properties of solar materials themselves or designing device architectures that improve charge extraction or photon management. The work presented here pursues both of these strategies by leveraging a central feature of solution-processed solar cells - the ability to control the composition of the active layer by simply blending different ingredients in the precursor solutions. This simple concept provides the opportunity to tune the chemical composition of ionic solar materials, adjust the kinetics of film formation, add passivating agents that reduce trap densities, or introduce nanomaterials with specialized functionality into the active layers. To explore this concept, two specific projects were undertaken. The first evaluates how the light harvesting ability of bulk-heterojunction systems is impacted by incorporating plasmonic nanoparticles into the material bulk. By performing a series of finite-difference time-domain (FDTD) calculations, many different active layer compositions were screened through to identify optimal optical configurations and predict performance trends. The results of this analysis informed the fabrication of actual solar cells, which generated photocurrent and external quantum efficiency enhancements consistent with the predicted trends. To fabricate several of these devices, biomolecules were used to mediate the assembly and growth of plasmonic metal-oxide nanocomposites. The second project evaluates how replacing a portion of the metal content in metal-halide perovskite solar cells with alternative non-toxic metal species impacts the photovoltaic properties of the perovskite film. Relevant electronic properties such as the material band gap and carrier effective masses were theoretically evaluated using density functional theory (DFT). By computationally screening through a series of mixed-metal compositions that spans the periodic table, several promising candidates were identified that preserve the excellent electronic properties of the methylammonium lead triiodide perovskite, MAPbI3, while simultaneously reducing material toxicity. The computational effort was paired with an exhaustive experimental screening study that systematically evaluated how replacing various amounts of lead with nine different metal species influence material properties and photovoltaic performance. By screening through a large set of active material compositions both computationally and experimentally, favorable embodiments were encountered and the experimental results were benchmarked against the theoretical predictions to help speculate on the mechanisms responsible for observed performance improvements.

This book was released on 2017 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perovskite hybrid solar cells (Pero-HSCs) are rising stars in the nowadays photovoltaic(PV) technology. Within couple of years, the efficiency of perovskite solar cells has evolutionarily reach 22%, which override other types of solar cell by its low cost and ease to assemble. In theory, the Pero-HSCs has an upper conversion efficiency as 31%, therefore there are huge potential to be fulfilled in the near future research. In this work, we mainly focused on strengthening the electron extraction and transportation in the lead methylammonium tri-iodide(MAPbI3) perovskite solar cells. After a brief introduction on the origins and working principles of perovskite solar cells (Chapter ¿), the optimization of the cathode interface layer is addressed (Chapter ¿). Followed, a bulk heterojunction perovskite device was assembled by asserting n-type nanoparticles into perovskite layer for the first time (Chapter ¿). Last, the significance of this work and outlook was analyzed in Chapter ¿.Interfacial engineering of conventional perovskite solar cell is investigated by adopting a ternary metal oxide, Zn2SnO4 (ZSO), as electron extraction layer(EEL). Compared with generally used ZnO (ZO), thin film of ZSO nanoparticles(NPs) possess higher transparency over the entire visible wavelength, and is low temperature (=100 oC) annealed. Combined with more favorable energy level for electron extraction as cathode interface layer and higher electron conductivity, a dramatically boost in short circuit current density (JSC) and accordingly higher power conversion efficiency(PCE) were observed. Device engineering of inverted structured perovskite solar cells by incorporating either ZO NPs or ZSO NPs into the perovskite layer to form bulk heterojunction is discussed. Owning to the improved carrier mobility and much more balanced e-h transport, charge recombination was largely suppressed, the enlarged VOC, JSC and fill factor(FF) was obtained, corresponding to a 25% augment in PCE compared with planar perovskite device.

This book was released on 2020 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solar energy has the highest capacity to power our energy needs sustainably without emitting greenhouse gases. Hybrid organic-inorganic lead halide perovskite solar cells (PVSCs) have emerged in the past decade as a promising low-cost, low energy intensity, thin film solar cell with lab efficiencies reaching 25.2%. The toxicity of Pb perovskites and performance and stability issues with Sn lead-free alternatives remains a major roadblock to commercialization. In this work, novel perovskite compositions are designed and used to study the transition from Pb to Sn perovskites, cations are tuning to implement stabilizing components for pure Sn perovskites, and Sn perovskites performance and stability issues are tackled. The triple cation methylammonium (MA), formamidinium (FA) and Cs, with double halide composition Csx(MA0.17FA0.83)1-xPb1-ySny(I0.83Br0.17)3 films with x = 0.05, 0.10, and 0.20 and y = 0, 0.25, 0.50, 0.75, and 1.0 was used to create a library of new perovskites and study novel band gap trends near the maximum Schockley Quiesser limit. The simple inverted device structure of indium tin oxide (ITO)/poly (3,4, -ethylenedioxythiphene): polystyrene sulfonate (PEDOT:PSS)/Perovskite/[6,6]-phenyl-C60-butyric acid methyl ester (PC60BM)/fullerene (C60)/2,9-dimethyl-7,7-diphenyl-1,10-phenanthroline (BCP)/Ag eliminated dopant instabilities. Due to a high-quality film morphology and optimal bandgap, 3 3 Cs0.05(MA0.17FA0.83)0.95Pb0.25Sn0.75(I0.83Br0.17)3 (band gap = 1.30 eV), achieved a record maximum efficiency of 11.05% for any 75% Sn composition. Moreover, the 75% Sn PVSCs retained 80% of initial PCE after 30 days storage in inert conditions and 100 hours in ambient conditions. After optimizing antisolvent choice, solvent annealing, and hot casting conditions for pure Sn perovskite films, the novel composition with Cs, FA, and guanidinium (GA), (CsGA)xFA100 2xSnI3 was implemented. This cation mixture combines the benefits of a guanidinium cation, such as increased hydrogen bonding and no dipole moment, with Cs to fill point defects and relax the crystal lattice to better integrate a large stabilizing agent, ethylenediammonium diiodide (EDAI2). The EDAI2 additive not only yielded pinhole-free cubic phase (CsGA)xFA100-2xSnI3 perovskite films but also decreased both shallow and deep trap states in the perovskite films. The devices with (CsGA)15FA70SnI3 and 0-2% EDAI2 all achieved a maximum PCE higher than 5% with the highest of 5.72% for a fresh device with (CsGA)15FA70SnI3 and 1% EDAI2. After storage, the maximum PCE was increased from 5.69% to 6.39% for the (CsGA)15FA70SnI3 and 1.5% EDAI2 devices. Finally, to tackle energy loss issues that have plagued pure Sn perovskites (loss = 0.6-0.9 V), the misalignment between the PEDOT:PSS hole transport layer and the Sn perovskite valence band was studied due to the energy misalignment between the hole transport layer and pure Sn perovskite valence band. Cosolvent methods, solvent wash methods, and solvent immersion methods with DMSO, EG, and CH3OH were implemented to alter the PSS content and work function of the HTL to improve alignment. Utilizing the (CsGA)15FA70SnI3+1.0% EDAI2 perovskite film we demonstrated a higher performance of 6.29% and 6.16% with a 5% DMSO cosolvent and methanol solvent wash, respectively. This work is a comprehensive push to improve the performance and stability of non-toxic Sn perovskite devices, bringing this technology one step closer to commercialization.

Download or read book Developing Highly Efficient Lead Halide Perovskite Solar Cells written by Jason Jungwan Yoo and published by . This book was released on 2020 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lead halide perovskite solar cells are an emerging technology that can be solution processed to yield low-cost, light weight and flexible photovoltaics. Much of the early work has been focused on developing device structures and processing techniques to improve light absorption and eliminate detrimental traps within the bulk of the perovskite active layer. As a result, the device efficiency of perovskite solar cells has improved from ~3% up to ~20% in less than a decade. However, the device efficiency of perovskite solar cells still need to be much improved in order to compete with traditional photovoltaic technologies, such as Silicon and GaAs, and to ultimately realize the theoretically determined Shockley-Queisser (SQ) efficiency limit. In this thesis, I focus on the development of a novel interface passivation strategy called selective precursor dissolution (SPD) strategy, that utilizes low dimensional 2D perovskites as the interface passivating layer. The post treatment of the bulk perovskite thin film with 2D perovskites via SPD strategy prevented formation of a detrimental non-perovskite phase at the interface and resulted in much improved thin film quality with reduced detrimental interface recombination. As a result, a certified power conversion efficiency (PCE) of 22.6% is achieved from a quasi steady-state measurement along with an electroluminescence (EL) efficiency up to ~9%. Both device metrics were the highest values reported at the time of publication. In addition to developing an interface passivation strategy to improve device performance, a high quality electron transport layer (ETL) was developed and a new perovskite composition was adopted to further improve the device performance. A chemical bath deposition (CBD) was used for the synthesis of a tin dioxide (SnO2) ETL. The pH of the reaction solution is identified as the key parameter for the CBD of SnO2 that controls the quality of the SnO2 ETL. pH 1.5 is determined to be the optimum acidity that results in a SnO2 ETL with compact and conformal coverage without producing a detrimental secondary crystal phase. To improve the optoelectronic properties of the perovskite active layer, MAPbBr3 is significantly reduced to minimize the band gap penalty, which also resulted in improved effective carrier mobility. MAPbBr3 is commonly added to the perovskite composition to stabilize the [alpha]-phase FAPbI3 but results in an increase in the band gap. Addition of 0.8 mol% of MAPbBr3 to the FAPbI3 perovskite resulted in much improved carrier lifetime and effective mobility, compared to conventionally added 10 mol%. Together with the new SnO2 and the perovskite active layer, a record setting and certified PCE of 25.2% is achieved, which translates to 80.5% of the SQ limit for its band gap. In addition, due to low open-circuit voltage (V[subscript OC]) loss, the newly developed devices exhibit an EL efficiency up to 17.2% and an EL wall-plug efficiency up to 21.6%. Both PCE and the EL efficiency is the highest reported so far from a single perovskite solar cell structure.
