p ‐Toluenesulfonic acid/dimethyl sulfoxide (PTSA/DMSO)‐treated poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)/crystalline‐silicon (c‐Si) hybrid solar cells with a solution‐processed anti‐reflection coating of TiO 2 exhibit a record power conversion efficiency of 15.5%. Additionally, the performance stability of the hybrid device for both air storage and light exposure is improved due to removal of the PSS matrix from the PTSA/DMSO‐treated PEDOT:PSS thin film.
