Abstract

original image

The photovoltaic properties of poly(3-pentylthiophene) (P3PT) are studied. P3PT-based polymer solar cells with IC60BA and IC70BA as acceptors demonstrate high power conversion efficiencies of 4.50% and 5.44% with high open-circuit voltages of 0.89 and 0.88 V, respectively. These devices benefit from the high-lying LUMO energy levels of IC60BA and IC70BA.
