Polyacetylene, (CH)x: Photoelectrochemical solar cell

Abstract

Photoelectrochemical photovoltaic cells have been fabricated using polyacetylene, (CH)_x, as the active photoelectrode. Using a sodium polysulfide solution as electrolyte, V_oc∼0.3 V and I_sc∼40 μA/cm² were obtained under illumination of approximately 1 sun. Under present conditions, the cell efficiency is limited by the series resistance, the small effective area of the electrode configuration, and the absorbance of the solution.
