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

摘要

Photoconductive devices are disclosed in which theconversion of light to electric energy is effected bymeans of an organic film of a novel photoconductivepolyimide compound having a carbazole skeleton in therepeating unit thereof. Photoelectric devices accordingto the invention are particularly useful in solar cellsand photosensors by reason of superior environmentalstability of the said polyimide compounds and their thin-film workability.
