摘要：

In this paper MoO3/ITO (molybdenum oxide/tin-doped indium oxide) is proposed as the window layer deposited on the hole transport layer in semi-transparent bifacial perovskite solar cells. The molybdenum oxide (MoO3) buffer layers with various thickness were prepared by evaporation. Given the PV Lighthouse simulation, the influence of MoO3 buffer layer on the cell performance was systematically analyzed. Taking advantage of the wide bandgap of the electron transport layer and the anti-reflection effect of MoO3/ITO layer stack, the short-circuit current density is improved as the cell illuminated from the glass substrate (SnO2 electron transport layer). It was shown that the fill factor and short-circuit current density reach the maximum when the thickness of MoO3 buffer layer is in the range of 10-15 nm, leading to the highest conversion efficiency. Finally, a semi-transparent bifacial perovskite solar cells with a bifacial rate of 69.5% was obtained. © 2021, Solar Energy Periodical Office Co., Ltd. All right reserved.
