Abstract
Hybrid lead-halide perovskite solar cells (PSCs) are promising alternatives to silicon-based cells due to their high photovoltaic performance and low cost. We report herein fully printable perovskite solar cells with a mesoporous TiO2/Al2O3/C architecture in combination with mixed-halide MAPbI3−xBrx perovskites. A maximum conversion efficiency of 13.49% can be achieved with an increased open circuit voltage of 1.01 V, which is higher than the MAPbI3-based devices. A reduced anomalous hysteresis in the J–V curve measurement has been demonstrated in perovskite solar cells based on MAPbI2.4Br0.6 perovskite, which is directly linked to the characteristically slow kinetics measured through electrochemical impedance spectroscopy.This publication has 48 references indexed in Scilit:
