Role of absorber and buffer layer thickness on Cu2O/TiO2 heterojunction solar cells

Cu2O/TiO2 heterojunction solar cells have bright prospective for application in photovoltaics. The low power conversion efficiency of these cells, though, is a matter of concern. In the present work, solar cells with Cu2O/TiO2 heterojunction have been analysed using software Solar Cell Capacitance Simulator (SCAPS). The effect of thickness of absorber layer and the buffer layer on the performance of the cell has been studied and these thicknesses has been optimised. The effect of temperature on the efficiency of Cu2O/TiO2 heterojunction solar cell has also been investigated.
