A transparent poly(3,4-ethylenedioxylenethiophene):poly(styrene sulfonate) cathode for low temperature processed, metal-oxide free perovskite solar cells
Low temperature processed, metal-oxide free planar perovskite solar cells (PSCs) were fabricated using polyetherimide (PEI) modified poly(3,4-ethylenedioxylenethiophene):poly(styrene sulfonate) (PEDOT:PSS) as the cathode.
