Abstract

We report on fabrication of 4-terminal all-perovskite tandem solar cells with power conversion efficiencies exceeding 23% by mechanically stacking semitransparent 1.75 eV wide-bandgap FA_0.8Cs_0.2Pb(I_0.7Br_0.3)₃ perovskite top cells with 1.25 eV low-bandgap (FASnI₃)_0.6(MAPbI₃)_0.4 bottom cells. The top cells use MoO_x/ITO transparent electrodes and achieve transmittance up to 70% beyond 700 nm.
