We report the use of a phenylalkyl side chain modified donor molecule to increase the open-circuit voltage (Voc) of an organic photovoltaic device. The bulky side chain is able to alter the donor/acceptor interface without interfering in the molecular packing. As a result, both Voc and device performance are improved.
