Abstract

We present photocurrent spectra of an ITO/Pt-poly-yne/Al photocell under vacuum after annealing and also after exposure to air. We find that air enhances exciton dissociation. We also find that a low energy photocurrent tail appears after exposure of the cell to air. The enhancement of the photovoltaic response to air is found to be reversible after annealing under vacuum.
