The photovoltaic properties of poly(3‐pentylthiophene) (P3PT) are studied . P3PT‐based polymer solar cells with IC 60 BA and IC 70 BA 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 IC 60 BA and IC 70 BA.
