Available in PDF, EPUB and Kindle. Book excerpt: Beginning with an overview and historical background of Copper Zinc Tin Sulphide (CZTS) technology, subsequent chapters cover properties of CZTS thin films, different preparation methods of CZTS thin films, a comparative study of CZTS and CIGS solar cell, computational approach, and future applications of CZTS thin film solar modules to both ground-mount and rooftop installation. The semiconducting compound (CZTS) is made up earth-abundant, low-cost and non-toxic elements, which make it an ideal candidate to replace Cu(In,Ga)Se2 (CIGS) and CdTe solar cells which face material scarcity and toxicity issues. The device performance of CZTS-based thin film solar cells has been steadily improving over the past 20 years, and they have now reached near commercial efficiency levels (10%). These achievements prove that CZTS-based solar cells have the potential to be used for large-scale deployment of photovoltaics. With contributions from leading researchers from academia and industry, many of these authors have contributed to the improvement of its efficiency, and have rich experience in preparing a variety of semiconducting thin films for solar cells.

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method for synthesizing a thin film of copper, zinc, tin, and a chalcogen species ('CZTCh' or 'CZTSS') with well-controlled properties. The method includes depositing a thin film of precursor materials, e.g., approximately stoichiometric amounts of copper (Cu), zinc (Zn), tin (Sn), and a chalcogen species (Ch). The method then involves re-crystallizing and grain growth at higher temperatures, e e.g., between about 725 and 925 degrees K, and annealing the precursor film at relatively lower temperatures, e.g., between 600 and 650 degrees K. The processing of the precursor film takes place in the presence of a quasi-equilibrium vapor, e.g., Sn and chalcogen species. The quasi-equilibrium vapor is used to maintain the precursor film in a quasi-equilibrium condition to reduce and even prevent decomposition of the CZTCh and is provided at a rate to balance desorption fluxes of Sn and chalcogens.

Available in PDF, EPUB and Kindle. Book excerpt: The world energy consumption has increased rigorously in recent years due to the rapid economic development and the massive global population expansion. Today the world energy supply relies heavily on fossil fuels, known as non-renewable energy resources, which have limited reserves on Earth and do not form or replenish in a short period of time. Burning fossil fuels not only brings environmental pollutions but also results in carbon dioxide and other greenhouse gases, which are to blame for global warming. Therefore, to build a more sustainable and greener future, we have to develop alternative renewable energy resources. Photovoltaic (PV) cell, also commonly known as solar cell, is a very promising renewable energy technology. Here in this dissertation, we have studied two emerging PV materials with earth abundant elements, i.e. copper zinc tin sulfide (CZTS) and organic-inorganic hybrid halide perovskite. Having earth abundant elements means that the raw materials have rich reserves on Earth and the costs are relatively low. It also means that the materials have the potential capability to be produced in large scales in industry. We first explored two different deposition methods for preparing CZTS thin films. In the first method, the CZTS was fabricated by a solution based method with diethyl sulfoxide (DMSO) as the solvent and the effect of spin speed on the properties of CZTS thin films was studied. The results indicated that a higher spin speed was more favorable for attaining a more densely packed and pinhole-free film while no crystallographic differences were observed. In the second method, CZTS was fabricated using sputtered metal precursors followed by a closed-space sulfurization (CSS) technique, which had high manufacturing compatibility and could be applied in industry. After exploring different sulfurization conditions, including temperatures and time, the champion cell was obtained at 590oC for 30min, with a maximum power conversion efficiency (PCE) of 5.2%. We then explored three different organic-inorganic hybrid halide perovskite materials for solar cell applications. The first perovskite material is methylammonium tin triiodide (MASnI3, bandgap ~1.3 eV). It was fabricated by a hybrid thermal evaporation. The as-deposited MASnI3 thin films exhibit smooth surfaces, uniform coverage across the entire substrate, and strong crystallographic preferred orientation along the 100 direction. Our results demonstrate the potential capability of the hybrid evaporation method for preparing high-quality MASnI3 perovskite thin films which can be used to fabricate efficient lead (Pb)-free perovskite solar cells (PVSCs). The second perovskite material is mixed-cation (formamidinium and cesium) lead iodide (FA0.8Cs0.2PbI3). We find that one of the main factors limiting the PCEs of FA0.8Cs0.2PbI3 PVSCs could be the small grain sizes, which leads to relatively short mean carrier lifetimes. We further find that adding a small amount of lead thiocyanate additive can enlarge the grain size of FA0.8Cs0.2PbI3 perovskite thin films and significantly increase the mean carrier lifetime. As a result, the average PCE of FA0.8Cs0.2PbI3 PVSCs increases from 16.18 ± 0.50 (13.45 ± 0.78)% to 18.16 ± 0.54 (16.86 ± 0.63)% when measured under reverse (forward) voltage scans. The best-performing FA0.8Cs0.2PbI3 PVSC registers a PCE of 19.57 (18.12) % when measured under a reverse (forward) voltage scan. The third perovskite material is FA0.8Cs0.2Pb(I0.7Br0.3)3 (bandgap ~1.75 eV). We find that the cooperation of lead thiocyanate additive and a solvent annealing process can effectively increase the grain size of the perovskite thin films while avoiding the undesired excess lead iodide formation. As a result, the average grain size of the FA0.8Cs0.2Pb(I0.7Br0.3)3 perovskite thin films increases from 66 ± 24 nm to 1036 ± 111 nm and the mean carrier lifetime shows a more than 3-fold increase, from 330 ns to over 1000 ns. As a result, the average open-circuit voltage (Voc) of FA0.8Cs0.2Pb(I0.7Br0.3)3 PVSCs increases by 80 (70) mV and the average PCE increases from 13.44 ± 0.48 (11.75 ± 0.34)% to 17.68 ± 0.36 (15.58 ± 0.55)% when measured under reverse (forward) voltage scans. The best-performing wide-bandgap (~1.75 eV) PVSC registers a stabilized PCE of 17.18%, demonstrating its suitability for top cell applications in all-perovskite tandem solar cells.

This book was released on 2014 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Semiconductor nanoparticles have been an important area of research in many different disciplines. A substantial amount of this work has been put toward advancing the field of photovoltaics. However, current p-type photovoltaic materials can not sustain the large scale production needed for future energy demands due to their low elemental abundance. Therefore, Earth abundant semiconductor materials have become of great interest to the photovoltaic community especially, the material copper zinc tin sulfide (CZTS), also known by its mineral name kesterite. CZTS exhibits desirable properties for photovoltaics, such as elemental abundance, high absorption coefficient (~104 cm-1), high carrier concentration, and optimum direct band gap (1.5 eV). To date, solution based approaches for making CZTS have yielded the most promising conversion efficiencies in solar cells. To that end, the motivation of nanoparticle based inks that can be used in high throughput production are an attractive route for large scale deployment. This has driven the need to make high quality CZTS nanoparticles that possess the properties of the pure kesterite phase with high monodispersity that can be deposited into dense thin films. The inherent challenge of making a quaternary compound of a single phase has made this a difficult task; however, some of those fundamental problems are addressed in this thesis. This had resulted in the synthesis of phase-pure k-CZTS confirmed by powder X-ray diffraction, Raman spectroscopy, UV-visible absorption spectroscopy and energy dispersive x-ray spectroscopy. Furthermore, ultra-fast laser spectroscopy was done on CZTS thin films made from phase-pure kesterite nanoparticles synthesized in this work. This thesis provides new data that directly probes the lifetime of photogenerated free carriers in kesterite CZTS (k-CZTS) thin films.
