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 WO 3 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 CH 3 NH 3 PbI 3 (MAPbI 3 ), CH(NH 2 ) 2 PbI 3 (FAPbI 3 ), and FA 0.5 MA 0.38 Cs 0.12 PbI 2.04 Br 0.96 as the optical active layer, a solar cell with a device architecture of ITO/SnO 2 /perovskite/spiro‐OMeTAD/MoO 3 /Ag/WO 3 is fabricated. A series of efficient semitransparent PSCs with high transmittance are achieved.
