Abstract Enhancing the device electroluminescence quantum efficiency (EQE EL ) is a critical factor in mitigating non-radiative voltage losses (V NR ) and further improving the performance of organic solar cells (OSCs). While the common understanding

Complex morphology in donor/acceptor organic heterostructures hampers the understanding of device performance. Here, the origin of the high voltage loss in organic solar cells is ascribed to the too small spacing between the donor/acceptor molecules
