Manipulating molecular orientation at the donor/acceptor interface is the key to boosting charge separation properties and efficiencies of anisotropic‐materials‐based organic photovoltaics (OPVs). By replacing the polymeric donor PBDTBDD with its 2D‐conjugated polymer PBDTBDD‐T, the power conversion efficiency of OPVs featuring the anisotropic polymer acceptor PNDI is drastically boosted from 2.4% up to 5.8%.
