POLYIMIDE, ORGANIC FILM COMPRISING THE POLYIMIDE, AND PHOTOCONDUCTIVE DEVICE COMPRISING THE ORGANIC FILM

摘要

Photoconductive devices are disclosed in which the conversion of light to electric energy is effected by means of an organic film of a novel photoconductive polyimide compound having a carbazole skeleton in the repeating unit thereof. Photoelectric devices according to the invention are particularly useful in solar cells and photosensors by reason of superior environmental stability of the said polyimide compounds and their thinfilm workability.
