Photoconduction of Poly (p-phenylenevinylene) Films

Abstract
Large photoconduction in PPV films prepared via sulfonium salt process was found. The photocurrent was proportional to 0.5–0.7th power of the intensity of incident light. This suggested that recombination of photo-generated carriers played an important role in the photoconduction in PPV films. Photocurrent spectrum showed a huge broad peakin a near infrared region at which optical absorption was very weak.
