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). (C) 2000 Elsevier Science B.V. All rights reserved.
