Abstract

Efficient bulk heterojunction (BHJ) photovoltaic cells (PVs) based on 5 wt. donors and C₇₀ were fabricated. Tris[4-(5-phenylthiophen-2-yl) phenyl]-amine (TPTPA)-based BHJ PVs show higher power conversion efficiency (η_PCE) than aluminum phthalocyanine chloride-based BHJ PVs. Although the absorption of AlPcCl is complementary to that of C₇₀, TPTPAs high hole mobility and symmetrical molecular structure are likely to be crucial contributing factors to the higher η_PCE. Phase separation occurs in the 5-TPTPA blend. The device was optimized via replacement of the bathocuproine buffer by a combination of 3,4,9,10-perylenetetracarboxylic bis-benzimidazole and bathocuproine. η_PCE of 5.96 is achieved because of the decreased series resistance.
