- W2891042963 abstract "Abstract We introduce Cu2O as a hole-transporting material in perovskite solar cells. Device modeling with a configuration of glass/fluorine-doped tin oxide/ZnO/perovskite/Cu2O/carbon was performed by SCAPS, a solar cell capacitance simulator. The simulation results indicate that the device performance is greatly dependent on the defect densities and thickness of the perovskite absorber. An absorber thickness of 500 nm was optimum for efficient light absorption. The defect states at the perovskite/ZnO interface had a stronger influence on solar cell performance than those at the Cu2O/perovskite interface; therefore, to further improve photovoltaic performance, we should pay particular attention to the perovskite/ZnO interface. Proper interface modification and passivation to lower defect densities of the interface below 1016 cm−3 was essential. The impact of acceptor density and hole mobility of the hole-transport layer on device performance further confirmed that Cu2O is a suitable hole-transport layer for perovskite solar cells. Finally, to achieve better photovoltaic performance, a back-contact material with a high work function is very necessary." @default.
