Abstract
It has been previously shown that incorporating alcohol/water-soluble conjugated polyelectrolytes (CPEs) as cathode interlayers can substantially enhance the open-circuit voltage (Voc) of bulk heterojunction polymer solar cells (PSCs). This improvement is attractive since there are only a few solution-based processing technologies that can enhance the Voc. In this article, the Voc enhancement effect of five distinct CPE materials was studied on three typical PSC device configurations, each using different donor materials. Significant Voc enhancement was observed in devices that contain a polyfluorene copolymer as the donor material. The origin of the Voc enhancement was investigated by examination of the dark currents.
