Non-radiative energy loss remains a critical limitation to further improving the efficiency of organic solar cells (OSCs), as charge generation is typically governed by charge-transfer (CT) states that intrinsically suffer from non-radiative recombination. Intra-moiety excitation (i-EX), a delocalized excitation capable of dissociating within acceptor domains, provides an alternative pathway that can reduce CT-mediated loss. However, its molecular regulation and intrinsic photophysical character
