Farrell and published by . This book was released on 2014 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The novel technique of initiated chemical vapor deposition (iCVD) was used to develop an all solid state dye-sensitized solar cell (DSSC) using a solid polymer electrolyte. iCVD was chosen for this process due to its advantage in polymerizing within high aspect ratio porous geometries. Poly(4-vinylpyridine) (P4VP) was synthesized via iCVD in a planar geometry on a silicon wafer to observe the effects of iCVD reaction conditions on the deposition rate and properties of the resulting thin film. P4VP-based DSSCs were fabricated in iCVD using previously described methods for other polymers. Using N-719 ruthenium dye, the DSSCs were fabricated and tested with linear sweep voltammetry. The results were compared to liquid-based DSSCs prepared using similar materials and methods without iCVD treatment. The deposition rate of iCVD has been found to have a positive, linear relationship to the ratio of monomer pressure to saturation pressure (PMono/PSat). This change is independent of how the reaction conditions were varied, as changes in pressure and temperature carried the same effect on deposition rate. The P4VP-based cells exhibited efficiencies up to 1.5% compared to the liquid-based cell efficiencies up to 3.1%, however the polymer cells had a fill factor that was up to 10% greater than that of the liquid cells. The average short-circuit current density for the P4VP-based cells was 4.14 ± 0.35 mA/cm2 compared to the liquid cell average of 10.42 ± 0.19 mA/cm2. The average open-circuit voltage for the P4VP-based cells was 0.516 ± 0.005 V compared to the liquid cell average of 0.490 ± 0.003 V.

Available in PDF, EPUB and Kindle. Book excerpt: The global energy consumption has been increasing at an alarming rate over the years. In 1998, it was 12.7TW, but in 2050, it is expected to be around 26.4 to 32.9TW and in 2100, it will increase up to 46.3 to 58.7TW. The yearly increase in global energy consumption is expected to result in the rise of demands towards natural resources such as coal, petroleum and natural gas. Since these natural resources take thousands of years to form, it is impossible to replace them in the same rate at which they are being consumed. Therefore, it is a well-known fact that with the shortage of resources there will be an unprecedented rise in the harvesting expenses. Hence, the reliability on the other sources of energy, which are renewable will rise. In the current scenario solar cells, which are also known as photovoltaic cell seem to be one of the promising options of renewable energy.The very first cohort of photovoltaic cells were constructed using crystalline silicon disks. The next batch was primarily built using semiconductors. These semiconductors were usually compounds of III-V type, like cadmium telluride and copper indium selenide/sulphide. The dye-sensitized solar cells (DSSC) which belong to the thin film group, emerged as a new class of low cost energy conversion devices with simple manufacturing procedures. Incorporation of dye molecules in some wide bandgap semiconductor electrodes was a key factor in developing photoelectrochemical solar cells with improved efficiency.In this book, we begin with a detailed explanation about the basics of solar cell technology and move on to overview some aspects of the historical background, present-scenario, currently popular applications and future prospects of dye sensitized solar cells. The structural aspects and working principle of this promising class of solar cells has been dealt in detail for providing a good understanding of the basics. Some novel schemes in preparation and assembly of dye sensitized solar cell have been presented from recent literature reports. The performance of nanocrystalline solar cell samples can be appreciably improved by optimizing the preparation technique, the class of the nanostructured materials, types of electrolyte, and high transparent conductive electrodes. Challenges associated with materials choice, nanostructured electrodes and device layers structure design are detailed. Recent trends in the development of nano-crystalline materials for DSSCs technology are introduced. Manufacturability and different approaches suggested for commercialization of DSSC for various applications are outlined and discussed in detail.

Available in PDF, EPUB and Kindle. Book excerpt: The dye-sensitized solar cell (DSC) is a photovoltaic converter that mimics natural photosynthesis. Like green plants and algae it uses a molecular absorber, the dye, to harvest sunlight and generate electric charges. Dye-sensitized solar cells are poised to replace existing technologies in «low density» solar-energy applications, especially in contexts where mechanical robustness and light weight is required. This book offers the first comprehensive look at this promising technology and aims to provide a graduate level text that brings together the fundamentals of DSC from three perspectives (materials, performance, and mechanistic aspects), as well as to serve as an advanced monograph that summarizes the key advances and lists the technical challenges remaining to be solved.

Available in PDF, EPUB and Kindle. Book excerpt: Semiconductors have been studied as electrodes in electrochemical systems since the mid-1950's. However, it was not until the 1970's that the search for alternative energy sources, especially solar energy, led to an enormous expansion in semiconductor electrode research. One attractive option for solar energy conversion is the semiconductor liquid-junction solar cell, which can be designed to produce either electrical power or fuel such as hydrogen. Consequently the number of papers published concerning semiconductor electrodes has rapidly increased. Previous books have principally focused on the underlying theory (largely from solid state physics) and principles of operation of all semiconductor electrodes. It therefore seemed both useful and appropriate to review the field with the intention of collating information for each semiconductor or family of semiconductors, with contributions from authors who are all recognized experts in their field. Each chapter is devoted to critically assessing the recent literature on a particular semiconductor or family of semiconductors.

Available in PDF, EPUB and Kindle. Book excerpt: Dye-sensitized solar cells (DSCs) offer a variety of advantages to typical silicon and thin film solar cells. And while the advantages of ease-of-processing and fabrication from low-cost, earth-abundant materials make DSCs an attractive technology, the efficiency of DSCs (13%) is still too low to compete with the current inorganic incumbents. Hence, new 'outside-of-the-box' strategies must be used to render DSCs competitive with current commercial technologies. This thesis describes my work on identifying losses in DSCs and 2 strategies to improve the efficiency of DSCs: the use of highly-soluble energy relay days to broaden the spectral response of DSCs, and the fabrication of semi-transparent solid-state DSCs to help improve the efficiency of inorganic devices in a tandem solar cell. Solid-state dye-sensitized solar cells (ssDSCs) have historically lagged behind their liquid-electrolyte counterparts in efficiency. To gain a better understanding of why this is so, we have developed accurate internal quantum efficiency (IQE) measurements for ssDSCs. By analyzing the IQE, it is found that while charge collection is efficient in ssDSCs, often charge injection is not. This analysis also shows that parasitic absorption by the Spiro-OMeTAD is an important loss mechanism in ssDSCs and suggests that stronger absorbing sensitizers are the most promising path to higher efficiencies. In DSCs, the roles of absorbing light, injecting charge, and blocking recombination are all given to the sensitizing dye, resulting in a myriad of design rules for DSC sensitizers. An energy relay dye (ERD) is a second dye that helps relax these design rules by providing complementary absorption and then transferring energy to a sensitizing dye. However, such ERDs come with their own design rules, including the need for high solubility for full light absorption, and high photoluminescence for efficient energy transfer. We have designed and synthesized two such dyes, and characterized them as ERDs in DSCs, yielding a 65% increase in efficiency. Finally, even if DSCs are unable to reach efficiencies that render them competitive against traditional inorganic solar cells, DSCs can be used in conjunction with an inorganic solar cell in a hybrid tandem photovoltaic (HTPV). High open-circuit voltages and cheap processing render DSCs attractive top cells in HTPVs, and such devices can exceed efficiencies of 20%. However, in order to be used in HTPVs, a DSC must be fabricated such that below bandgap light can pass through the device and be absorbed by the inorganic bottom cell. Toward that end, we have developed a transparent top contact for solid-state dye-sensitized solar cells that renders ssDSCs attractive candidates for HTPVs.
