The effect of fullerene doping on photoelectric conversion using titanyl phthalocyanine and a perylene pigment

Abstract The effect of fullerene (C 60 ) doping on photoelectric conversion using titanyl phthalocyanine (TiOPc) and a perylene pigment, N, N′ -dimethyl-3,4 : 9,10-perylenebis(dicarboximide) (MPCI), was investigated. A new three-layer cell, ITO/MPCI/C 60 -doped TiOPc/TiOPc/Au, exhibited a higher quantum yield for charge-carrier photogeneration than a two-layer cell without the C 60 -doped TiOPc layer, ITO/MPCI/TiOPc/Au, upon irradiation with monochromatic light which TiOPc mainly absorbs. The three-layer cell showed a high conversion efficiency of 0.63% for incident white light at an intensity of ca. 100 mW cm −2 .
