Investigation of Organic Photoconductors

Abstract

Organic electron devices are now widely studied for its merits of large area production, ultra thin, ultra light weight, lower process temperature and flexible. One of fascinating characteristics is a larger photosensitivity. By utilizing this feature, organic photo-sensing devices are investigated. Especially in a photodiode, gain of the photocurrent was at most unity and higher photocurrent will not be expected. In this paper, we have investigated organic photoconductor, which has higher gain than the photodiode and preliminary experimental results were shown.
