    Optimal hole extraction performance in MoOx-incorporated PEDOT:PSS films for organic photovoltaics

    We propose a hole extraction system based on the metal-like poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) blended with MoOx. Tuning the volume ratio of MoOx to PEDOT:PSS, the conductivity i...
