Polyacetylene thin film photovoltaic devices

Abstract

Photovoltaic devices have been obtained by a direct polymerization of undoped (or p-type doped) thin film (CH)x layer onto a polycrystalline cadmium sulfide film. The morphology of the contact is observed by S.E.M. microscopy. The electrical characteristics of this device are studied in the dark or under illumination. The main result, at AM1, 100 mW/cm2 with doped (CH)x correspond to 0.5 percent efficiency.
