Abstract

A semitransparent perovskite solar cell (PSC) with a dielectric/metal/dielectric (DMD) multilayer film as the top transparent electrode is investigated. Through adjusting the thickness and the deposition rate of Ag and WO3 layers, a transparent electrode with a low sheet resistance of 7 Ω sq−1 and high average visible transmittance (AVT) of 73% in the visible wavelength range of 400–800 nm is obtained. Using the resultant DMD film as the top transparent electrode and different bandgap perovskites of CH3NH3PbI3 (MAPbI3), CH(NH2)2PbI3 (FAPbI3), and FA0.5MA0.38Cs0.12PbI2.04Br0.96 as the optical active layer, a solar cell with a device architecture of ITO/SnO2/perovskite/spiro-OMeTAD/MoO3/Ag/WO3 is fabricated. A series of efficient semitransparent PSCs with high transmittance are achieved.
