Abstract: Minimizing energy loss and increasing the field factor are key aspects to transcend the current limitations on the performance of organic photovoltaics (OPV).Our recent study on charge recombination in BHJ and Planar-Mixed Heterojunction (PMHJ) has shown both high photovoltaic internal quantum efficiency and high external electroluminescence quantum efficiency. Moreover, a new concept of applying ”Dilution Effect” is introduced to explain the commonly observed composition-dependent Voc and reduced photovoltage loss in highly efficient ternary-based devices due to significantly reduced phonon-electron coupling. At the end, several novel interface engineering approaches will be introduced.By integrating highly efficient OPV with perovskite, stable hybrid solar cells with PCE of >24% were achieved.
