Combinatorial studies of organic thin-film photovoltaic cells (see Figure) can identify the separate optical and electronic contributions to the photocurrent. A second charge-transfer zone is proposed to explain the observed augmentation of the short-circuit current induced by an additional TiO2 layer. The ratio of the exciton diffusion lengths in copper phthalocyanine (CuPc) and a perylene dye (DMPTI) is estimated to be ≈ 8:5.
