In article number 1600228, Taiho Park, Sang Kyu Lee and co-workers achieve a high efficiency of 7.45% in a 77.8 cm2 rigid module of organic photovoltaics. The delicate control of intermolecular interaction has an important role in achieving a well-interconnected morphology. The number of 2D-BDT (benzodithiophene) units is essential in creating a well-defined intermolecular interaction, and the desired interconnected bulk heterojunction structure.
