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[sub 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[sub 60]. Photogeneration efficiency of unity at an applied electric field of 55 V/μm is found in one composite. © 2000 American Institute of Physics. [ABSTRACT FROM AUTHOR] |
