Abstract

original image

The photovoltaic properties of poly(3-pentylthi-ophene) donors are studied by Y. F. Li and co-workers on page 966 by fabricating polymer solar cells (PSCs) with PCBM, IC60BA or IC70BA as the acceptor. The P3PT-based PSCs with IC60BA and IC70BA demon-strate higher power-conversion efficiencies of 4.50% and 5.44% with high open-circuit voltages of 0.89 and 0.88 V, respectively, compared with PCBM, benefiting from their higher-lying LUMO energy levels.
