摘要：

We have fabricated photovoltaic devices using poly (p-phenylene vinylene) (PPV) as the active layer and poly (3,4 ethylenedioxythiophene) (PEDOT) doped with polystyrene sulfonic acid (PSS) and aluminium as electrodes. We have compared the performance of these devices with a device where indium-(in oxide OTO) was used as electrode. Using PEDOT the spectrum of the external quantum efficiency is constant in a broad range of energy, while devices made with ITO show only a very narrow peak at the onset of the absorption. When PPV is converted on top of PEDOT the photoluminescence is more quenched than on top of ITO, suggesting interfacial reactions between PPV and PEDOT:PSS.
