From a base material of conductive polymer (poly-(3,4-ethylenedioxythiophene):poly(styrenesulfonate), PEDOT:PSS), a flexible and high-conductivity (as low as 45 Ω/sq) transparent electrode was fabricated on polydimethylsiloxane elastomer by an acid treatment and transfer process. Combined with the D-sorbitol-doped PEDOT:PSS electric glue, we successfully demonstrated a vacuum-free and ambient lamination fabrication process for semi-transparent perovskite solar cells using triple cation Cs005(MA017FA083)095Pb(I083Br017)3 perovskite. By this manufacturing-friendly lamination process, we fabricated semi-transparent perovskite solar cell devices with power conversion efficiencies up to 16.4% and variable transparencies.
