Optimization Materials, Technologies, Deposition Methods of Thin Films Solar Cells: A Review

Deepak Suthar, Vinay Sharma

Thin film solar cells offer the most promising and potentially important alternative for the substantially reducing the cost of photovoltaic system. This is may be the future of sustainable energy for the human civilization. A multiplicity of option in terms of materials and device are currently being developed worldwide. Day by day photovoltaic cells have been increased demands everywhere in the worldwide. The shortage of silicon supplies scientists have been tested the new semiconductor applications for solar cells. We also told that along with the silicon wafer we can also use other categories of solar cells such as cadmium chloride, CIGS, gallium arsenide, zinc telluride and organic solar cells that are having low cost and high efficiency. In the latest the performance of perovskite photovoltaics is greatly affected by undesirable defects that contribute to non-radiative losses and mitigate these losses by doping perovskite with KI to alter the dielectric response, thus defect capturing probability, resulting in inverted device with PCE of 22.3% and low voltage loss. In this review article mentioned that the much type of solar cells along with the higher efficiencies, their cost is effective and which is most useful fabrication method.
