"In this work, a semi-transparent, low-cost and easy processable graphene derivative and PH1000 (conductive PEDOT:PSS polymer) based bilayer anode, is presented as a sustainable potential alternative to ITO (Indium Tin Oxide). The simple mechanical-synthesized graphene derivative was in aqueous-suspension processed (SPG), drop-coated onto a common glass substrate and treated with hydriodic acid (HI). Modified PH1000 with dimethyl sulfoxide (DMSO) was spin-coated onto SPG layer. The bilayer anode (SPG/PH1000) exhibited an adequate transmittance and resistance and it was used in the manufacture of organic solar cells (OSCs) based on the non-fullerene PBDB-T:ITIC active layer."
