Platinum‐Complex Acceptor Modulating Dielectric Constant and Exciton‐Vibration Coupling for High‐Efficiency Organic Solar Cells with Suppressed Energy Loss

and superior exciton separation, culminating in a remarkably high power conversion efficiency (PCE) of 20.52%. This work highlights the crucial role of metal-complex acceptors in managing energy loss and charge dynamics, thus providing a molecular design paradigm to develop highly efficient organic photovoltaics.
