Compared to 3D MAPbI3 thin films, (PEA)2(MA)n-1PbnI3n+1/MAPbI3 2D/3D bilayer thin films not only possess larger crystals, but also exhibit enhanced build-in potentials, suppressed charge carrier recombination, boosted charge carrier transport, and shortened charge carrier extraction time. As a result, perovskite solar cell by (PEA)2(MA)n-1PbnI3n+1/MAPbI3 2D/3D bilayer thin films exhibit 22.13 % power conversion efficiency with dramatically enhanced stability. Moreover, at room temperature, perovskite photodetectors by (PEA)2(MA)n-1PbnI3n+1/MAPbI3 2D/3D bilayer thin films show a photoresponsivity of 1.38 AW-1, and a detectivity of 6.52 × 1014 Jones (1 Jones = 1 cm Hz1/2 W-1), and a linear dynamic range of over 167 dB. In CHAPTER III, the improved device performance of perovskite photovoltaics by one-step self-assembled (PEA)2(MA)79Pb80I241 thin film incorporating with 0.1% Nd3+ were exhibited. Compared with 3D MAPbI3 thin films, (PEA)2(MA)79Pb80I241: Nd3+ thin film not only possess larger crystal, but also shown enhanced build-in potentials, suppressed charge carrier recombination, boosted charge carrier mobility, and shortened charge carrier extraction time.

This book was released on 2021 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the world storage of coal, oil, natural gas, and other sources of nonrenewable energy is becoming less and less, meanwhile the problem of energy shortage is becoming more and more emergent which will restrict the development of the international economy. Under this background, most countries begin to develop solar energy, which promotes the development of solar cells. As we know, solar cells can straightforwardly transform light into electricity through the photovoltaic effect, and currently silicon solar cell is the most sophisticated technology in commercialization. Nevertheless, because of the complexity of the fabrication technique and the high cost of silicon materials, it is not easy to cut its price substantially. Therefore, finding new materials and new methods to fabricate economic solar cells is necessary. Right now, the hot research topic in this field is perovskite solar cells (PSCs). This kind of solar cell has a special light-absorbing active layer, which is called organic inorganic hybrid perovskite (OIHP), the most common is methylammonium lead iodide (CH3NH3PbI3 or MAPbI3). This kind of PSC can be easily solution-processed, and the raw materials are less expensive, both make it cheap to process and simple to fabricate. Previous studies have shown that perovskite like MAPbI3 with a three-dimensional (3D) structure are highly efficient. But the poor stability limits its application. Thus, it is urgent to develop a novel kind of PSCs with both high efficiency and good stability. Here, we present two feasible methods, compositional engineering and interfacial engineering, to fabricate 2D:3D mixed PSCs and 2D/3D bilayer PSCs for achieving the goal of high-performance photovoltaics. In the first method, with the help of 4-fluoro-phenethylammonium (4F-PEA) organic spacer, the corresponding champion PSC can obtain a better device performance with a power convention efficiency (PCE) over 20%, as well as a better stability for 3000 hours with less than 40% loss in PCE at a relative humidity of 10%-15%. This novel 2D:3D mixed [(4F-PEA)2MA[subscript n-1]Pb[subscript]I[subscript3n+1]][subscript x]:MAPbI3 perovskite will provide an innovative method to fabricate high-performance PSCs with good stability. In the second method, the surface defect passivation of MAPbI3 perovskite films with binary organic spacer 3-phenyl-2-propen-1-amine/4-fluoro-phenethylammonium (PPA/4F-PEA) is reported. We found that a 2D layer (PPA)(4F-PEA)MA[subscript n-1]Pb[subscript n]I[subscript 3n+1] can be formed on the surface of MAPbI3 perovskite and achieve more efficient PSCs by reducing defects and inhibiting non-radiative recombination. The results show that the PCE of this kind of PSCs can reach above 20%. In addition, a open-circuit voltage (V[subscript OC]) up to 1.16 V can be obtained with the presence of the top 2D layer, which is 93% of Shockley-Queisser limit V[subscript OC] (1.25 V). Because of the hydrophobic nature of the top 2D layer, the optimized PSCs can maintain 97% of the initial PCE after 500 hours at a relative humidity of 10%-15%. The unique idea of the 2D layer as a moisture-proof protection window, maintaining efficient 3D perovskite structure provides clues for the development of high-performance perovskites and paves the way for the wide application of efficient and stable PSCs shortly.

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.

This book was released on 2015-04-30 with total page 684 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since their discovery in 1977, the evolution of conducting polymers has revolutionized modern science and technology. These polymers enjoy a special status in the area of materials science yet they are not as popular among young readers or common people when compared to other materials like metals, paper, plastics, rubber, textiles, ceramics and composites like concrete. Most importantly, much of the available literature in the form of papers, specific review articles and books is targeted either at advanced readers (scientists / technologists / engineers / senior academicians) or for those who are already familiar with the topic (doctoral / postdoctoral scholars). For a beginner or even school / college students, such compilations are bit difficult to access / digest. In fact, they need proper introduction to the topic of conducting polymers including their discovery, preparation, properties, applications and societal impact, using suitable examples and already known principles/knowledge/phenomenon. Further, active participation of readers in terms of "question & answers", "fill-in-the-blanks", "numerical" along with suitable answer key is necessary to maintain the interest and to initiate the "thought process". The readers also need to know about the drawbacks and any hazards of such materials. Therefore, I believe that a comprehensive source on the science / technology of conducting polymers which maintains a link between grass root fundamentals and state-of-the-art R&D is still missing from the open literature.
