Abstract:
Ternary organic solar cells incorporating a dimer acceptor with oligo(ethylene glycol) side chains achieve 20.34% efficiency and enhanced thermal stability (T80 = 180 h at 80 °C), while also enabling non-halogenated solvent processing (19.68% PCE). This work highlights dimer acceptor side-chain engineering as a promising strategy for achieving high-performance and sustainable OSCs.
