Abstract
- 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. [ABSTRACT FROM AUTHOR]
