Photovoltaic performance of organic solar cells is highly dependent on the anisotropic nature of optoelectronic properties of photoactive materials. Here, we demonstrate an approach for highly efficient planar heterojunction solar cells by tuning the molecular orientation of the organic semiconducting materials. Face-on orientation of donor materials led to enhanced optoelectronic properties including light absorption, exciton diffusion, charge transport, and interfacial energetics. Enhanced exciton separation at the face-on donor-acceptor interface was observed as well. These results imply that the molecular orientation in photoactive layers is a critical factor that should be elaborately controlled for future high performance organic solar cells.
