The synthesis and characterization of a new series of anthracene‐based derivatives and their use as donors in bulk‐heterojunction solar cells is reported. It is found that when using well‐defined building blocks in constructing the chromophore, the donor molecular shape dramatically affects organic photovoltaic (OPV) performance in a previously unrecognized way.
