Performance improvement of highly stable molybdenum telluride solar cells with CZT BSF

Energy consumption is growing rapidly day by day since the development is directly proportional to the use of electricity. The conventional sources of energy are diminishing in response of huge energy consumption. So, the burning question is to explore new non-conventional sources of energy to meet the enormous demand. Solar energy is considered as potential source of alternative energy to build up sustainable development. Molybdenum Telluride (MoTe
₂
) is a very promising solar cell material for its power conversion efficiency and better thermal stability feature. In this study, it was investigated the performance of MoTe
₂
solar cell to explore the hidden potentiality by adding Cadmium Zinc Telluride (CZT) material used in back surface field between the absorber layer and final back contact metal. It was found in this research work that the possibility of high performance ultra-thin MoTe
₂
solar cells with better thermal stability. The highest power conversion efficiency of 25.15% was achieved for only 0.8 μm thickness of absorber layer.
