Abstract: The absorption spectrum, photoconductive action spectra of both sandwich and surface cells and Lux-Amere index for the evaporated film of αI-phthalocyanine copper (PcCu) have been measured. The relationship between the shapes of the absorption and photoconductive spectra depends on the ratio of the photocarriers recombination rate in the surface and the bulk of the evaporated film of PcCu. This is because the rate of the surface recombination of the sample is greater than the rate in the bulk; the photoconductive action spectrum of sandwich cell is in reverse in shape to the absorption spectrum in visible region; the photoconductive action spectrum of the surface cell is situated furthermore, between the above-mentioned cases of the two spectra. The sha-pes of the three spectra are similar in the near-infrared region owing to the bulk effect.
