摘要：
Perovskite-based inverted structure of solar cells with TiO2, graphene oxide (GO), and TiO2-GO photo-anodes were analyzed by SCAPS profile. The photovoltaic performance showed that GO produces the maximum power conversion efficiency of 10.34% under illumination. Quantum efficiency, carrier generation, recombination and concentrations through layers of devices were investigated. Then, the impact of GO thickness on photovoltaic characteristics was investigated to optimize the GO thickness. By optimizing the thickness of the GO layer, the efficiency of the device improved from 10.34% to 10.91% in the thickness of 40 nm. These simulation results could provide guidelines to fabricate higher efficiency solar cells.
