Abstract

An average PCE of 4.2% for all-polymer solar cells from 20 devices with an average J _SC of 8.8 mA cm^-2 are obtained with a donor-acceptor pair despite a low LUMO-LUMO energy offset of less than 0.1 eV. Incorporation of polystyrene side chains into the donor polymer is found to assist in reducing the phase separation domain length scale, and results in more than 20% enhancement of PCE. We observe a direct correlation between the short circuit current (J _SC) and the length scale of BHJ phase separation, which is obtained by resonance soft X-ray scattering.
