Modelling and performance analysis of perovskite solar cells for enhanced efficiency

Abstract

PSC finds fascinating applications in photodetectors, water photolysis, radiation detection and many more. Various endeavours have been made to consider efficiency, toxicity and stability of these cells. The major contributions of this research work are as follows: (1) The design of mixed halide perovskite solar cells has been demonstrated. It has been investigated that various parameters have efficacy to modify the PCE of the solar cell such as defect density, layer thickness, doping concentration etc. The use of copper oxide as the hole transport material has been analyzed. (2) CH3NH3PbI3-XClX with CuI and Cd1-XZnXS alloy as HTM and ETM respectively are investigated in order to determine their potential to be used as an alternative to the conventional possibilities. (3) Upto now the prime intention was to enhance the performance matrices, but environmental concerns also need to be considered, while designing PV devices. So in this regard, the design of Pb free perovskite solar cell has been demonstrated. The Copper antimony sulphide (CuSbS2) which is inorganic material is used as HTL in conjunction with the MASnI3 active layer because of its inherent features. The outcomes demonstrate that the Pb free MASnI3 perovskite solar cell is a future perspective to the photovoltaic community in terms of environment friendly nature and yielding comparative high efficiency as of lead based halide perovskite cell. newline
