摘要：

The mean free path length for excitons was determined in flat organic dye films. From simulations of the photocurrent response of solar cells, consisting of n-type perylene tetracarboxy diimide and a p-type organic dye, we found an exciton diffusion length of 30+/-10 Mn for zinc phthalocyanine (ZnPc), and 7+/-3 nm for zinctetra-(octylphenyl)-porphyrin (ZnTOPP). The value for ZnTOPP was independently confirmed by the luminescence quenching observed in ZnTOPP layers doped with a variable concentration of quenchers. The results show the direct correlation between the photovoltaic yield of a macroscopic device and the process of energy migration on a molecular scale. (C) 1998 Elsevier Science B.V.
