Abstract

Photoconductivity of organic polymers is reviewed. The current views on the mechanism of charge carrier generation and transport in sensitized and unsensitized polymers are presented. The known photoconductive polymers are categorized according to their structure into three basic groups: polymers with high degree of conjugation in the main chain, polymers with condensed aromatic groups and polymers with substituted arylamino functional groups.

Keywords
