Abstract: Photogeneration of carriers was measured at 633 nm in a series of polymer composites based on polystyrene, doped with a triphenyldiamine derivative as hole transport molecule and C-60 as sensitizer. Light absorption and generation of mobile carriers was achieved through the charge-transfer (CT) complex formed between the hole transport molecule and the sensitizer. We discuss the influence of the ionization potential of the hole-transport molecule on the photogeneration efficiency of the CT complex it forms with the sensitizer C-60. Photogeneration efficiency of unity at an applied electric field of 55 V/mu m is found in one composite. (C) 2000 American Institute of Physics. [S0021-9606(00)70221-2].
