Dielectric effect on the photovoltage loss in organic photovoltaic cells.

Song Chen1, Sai-Wing Tsang, Tzung-Han Lai, John R Reynolds, Franky So.   

Abstract

The VOC loss in several polymer-fullerene solar cells is determined. Based on these data, a major source of photovoltage loss is attributed to the low dielectric constants of the polymers. Such loss is close to zero if the dielectric constant of the polymer-fullerene blend is close to 5.
