摘要：

Co-deposited films of metal-free phthalocyanine and perylene pigments evaporated on a cooled substrate were found to generate a considerably large photocurrent. These films have an ultramicrostructure consisting of nanocrystals of perylene pigment covered with amorphous phthatocyanine. The efficient photocurrent generation can be explained by the large area of contact between the two pigments and the formation of individual routes for both photogenerated electrons and holes. A power conversion efficiency of 1% was observed in a three-layered cell incorporating a co-deposited interlayer fabricated under low-temperature conditions.
