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. All authors contributed to discussing the results and writing and reviewing the manuscript. Thin Solid Films 535, 10—13 2013. Annealing of thin films lowers the defect content, increases crystallite size, and induces recrystallization, which can improve the power efficiency of solar cells. Common phases include ZnS, SnS, CuS, and Cu 2SnS 3. The effect of strain distribution on abnormal grain growth in Cu thin films. This book will aid materials scientists and engineers in identifying research priorities to fulfill energy needs, and will also enable researchers to understand novel semiconductor materials that are emerging in the solar market.

In 2013 Rajeshmon et al. The reflections could also be indexed as 112, 200, 220, 312 and 332. The film annealed for 75 min shows the non-uniform texture, with some voids or cavities. Generally, annealing for an extended period assists the diffusion of each element and leads to the formation of homogeneous films. Category: Science Author : M.

A total of 20 mg Sulfur was evaporated from pellets 99. Phase equilibria in the Cu-Se system. Despite continued rapid cost reduction, concerns about material price and availability as well as toxicity have been raised. Structural determination via techniques like is hindered by disorder of the Cu-Zn cations, which are the most common defect as predicted by theoretical calculations and confirmed by neutron scattering. The result is an expert insight the central questions surrounding photovoltaic materials and systems, reflecting the latest developments in this hot and timely green topic. This low carrier lifetime may be due to high density of active defects or recombination at grain boundaries.

Japanese Journal of Applied Physics. Copper Zinc Tin Sulfide Thin Films for Photovoltaics: Synthesis and Characterisation by Electrochemical Methods. Advances in materials research have been the basis for much of this progress - resulting in reduced costs and improved conversion efficiencies and reliabilities for solar systems. Before annealing, a drying step is carried out at 200—300 °C to maximize solvent evaporation. Renewable and Sustainable Energy Reviews. However, some reports indicate that intermediates like binary sulfide of the constituent elements, bimetallic alloys or ternary Cu xSnS y can form at these temperatures. The possibility of fabricating these devices using low-cost and scalable electroplating is demonstrated.
