Abstract

Photoelectrical properties of high density trans-polyacetylene prepared by using a new type of catalyst have been studied. A strong dependence of photogeneration efficiency on the external electric field and the time evolution of the photoelectrical sensitivity after application of voltage was observed. The influence of uncompensated ionized impurities (O 2 −) is discussed. The spectral behaviour of the polyacetylene/aluminium Schottky barrier solar cell was studied and explained by a new model based on the Onsager dissociation of the Coulomb-bound charge carriers in the field of the barrier.
