Synergistic Bimolecular Passivation Stabilizing Surface States for High Performance HTL‐Free Inverted Perovskite Solar Cells
The inevitable photothermal‐induced desorption of functional molecules at the perovskite film surface would resurge the passivated surface defect states and cause severe recombination, thereby affecting both photovoltaic performance and stability of perovskite solar cells (PSCs). Here, we report a synergistic bimolecul...
