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.
