Designing and optimization of perovskite solar cells using different electron-transporting materials

This paper presents a comparative study of organometal halide perovskite-based solar cells using two different transparent conducting oxides, including SnO2 and ZnO, as electron-transporting materials. Simulation is an interesting way of studying the behavior of every component of a solar cell device as well as analyzing the performance of the full device. A solar cell capacitance simulator (AMPS)-1D has been the tool used for numerical simulation of such devices. In this study, the inluences of thickness of absorber and ETMs, dopant concentration of absorber and ETM, and working temperature on the performance of photovoltaic solar cells are studied. The performance of both devices indicates the replacement of SnO2 by a ZnO layer. ZnO can be a good option to reduce the cost and increase the mobility of ETM for this type of solar cells.
