Fluoropolymer indium-tin-oxide buffer layers for improved power conversion in organic photovoltaics

Abstract

We investigate the effects of polytetrafluoroethylene PTFE on poly 3-hexylthiophene :phenylC61-butyric acid methyl ester P3HT:PCBM based organic photovoltaic OPV devices by inserting thermally evaporated PTFE films between indium-tin-oxide ITO and P3HT:PCBM layers. Significant improvement in terms of open-circuit voltage, short-circuit current, and thereby… (More)
