By a combination of side chain and ternary blend strategies, novel BDT-TT-based copolymer donors were developed to improve the green solvent solubility, crystallinity, energy level, carrier mobility and blend morphology. Non-fullerene binary and ternary blend devices based on PTB-EDOTS exhibited high PCEs of 10.18% and 12.26%, respectively.
