High-Efficiency Organic Photovoltaic Cells Based on the Solution-Processable Hole Transporting Interlayer Copper Thiocyanate (CuSCN) as a Replacement for PEDOT:PSS

The use of copper thiocyanate (CuSCN) as a universal solution‐processable and highly transparent hole‐transporting layer in organic bulk‐heterojunction photo­voltaic cells is demonstrated. When CuSCN is employed as a replacement for the commonly used poly(3,4‐ethyl­­enedioxythiophene):polystyrenesul...

Description
Summary:The use of copper thiocyanate (CuSCN) as a universal solution‐processable and highly transparent hole‐transporting layer in organic bulk‐heterojunction photo­voltaic cells is demonstrated. When CuSCN is employed as a replacement for the commonly used poly(3,4‐ethyl­­enedioxythiophene):polystyrenesulfonate (PEDOT:PSS), organic solar cells with maximum power conversion efficiency of 8%, are realized; this value is 1.27 times higher than that for optimized control cells based on PEDOT:PSS.
