摘要：

The Au/H-2-phthalocyanine(H2Pc)/C-60/Au heterojunction shows a photovoltaic effect with the conversion efficiency of 0.02%. An electrically detected electron spin resonance (EDESR) study is done for this system. The observed EDESR signal represents a decrease of the photocurrent due to the spin-dependent recombination of the localized electron-hole pair which is created by the photoinduced charge transfer between the H2Pc and the C-60. The microwave-power-saturation behavior of the EDESR signal is not explained by the formula generally used. (C) 1997 Elsevier Science Ltd.
