“…Crystalline molecules are easily prepared as a templating layer (TL), such as pentacene and 2,5‐bis(4‐biphenylyl)‐bithiophene (BP2T) film. Introduction of a BP2T film to control the molecular growth of coevaporated zinc phthalocyanine (ZnPc) and C 60 blended films resulted in a 125% enhancement in the power conversion efficiency ( η PCE ) .…”

This work demonstrates the photocurrent enhancement in planar heterojunction (PHJ) photovoltaics via structural templating by a thin layer of dinaphthothienothiophene (DNTT) or 3,4,9,10‐perylene‐tetracarboxylic‐dianhydride (PTCDA). The use of a 10‐nm‐thick DNTT templating layer leads to a 43%, 13%, and 9% enhancement in the short‐circuit current for the subphthalocyanine (SubPc), copper phthalocyanine and chloroaluminum phthalocyanine based PHJs, respectively. A 1‐nm‐thick PTCDA templating layer also results in a 9% enhancement in the photocurrent from the SubPc/C60 PHJ cell, though less significant than the DNTT template. The mechanism of the photocurrent enhancement by introducing the two templating layers is discussed. A thin templating layer is introduced between the MoO3 and subphthalocyanine layers to enhance the photocurrent.
