 The incorporation of CDC at ZNS quantum dots, QDs, into a Pettit, PSS whole extraction layer, HEL, in UV-durable organic solar cells, OSCs, improves their UV durability by increasing the electric conductivity in the Pettit, PSS layer through hydrogen bond interactions between the Pettit units and PSS chains, which transforms the quinoid structure to an expanded coil structure. This modification also favors the efficient operation of non-foolerene acceptor, NFA, based OSCs by maintaining a high built-in potential across the bulk heterojunction.
