Abstract
The photosensitivity of a mixed composition of donor CuPc and acceptor C60, its degradation in time (for 16 months), and partial recovery (issues that were out of consideration previously) have been investigated. The sample is a simple nanostructure without encapsulation (quartz–SnO2–CuPc:C60–Al), the degradation of which is easier to analyze. It is shown that the process under study involves two mechanisms: slow (because of the decrease in the carrier lifetime) and relatively fast (because of the decrease in the internal field) degradations of the sample photosensitivity.
