• Photocurrent spectra of thin-film sandwich cells of vacuum-deposited phthalocyanines (Pc's) have been investigated and compared with their optical absorption spectra. A close resemblance was found between the two spectra for H_2Pc and ZnPc, but peaks in the photocurrent spectra of CuPc and NiPc have been found to be considerably shifted compared with those in the absorption spectra. These photocurrent peaks in CuPc and NiPc correspond well to structures in the recently reported electroabsorption spectra of phthalocyanines. Direct charge-transfer excitation is suggested to play a role in the photocarrier generation in phthalocyanine films. The absorption spectrum of V0Pc is considerably dependent on the deposition conditions of thin films, unlike other planar phthalocyanines.
