Paper Abstract

Photoeffects in phthalocyanine and perylene thin films and phthalocyanine/perylene hetero- p/n- and perylene/Au Schottky-cells were investigated in wavelength, temperature, and intensity dependent measurements. It is concluded that the charge carrier generation occurs only in a small region near or at a p/n- or Schottky type contact whereas the photoconductivity is a true bulk effect. Both types of photoeffects experience their own recombination processes leading to different intensity dependences.
