J52 is a medium bandgap semiconducting copolymer donor constructed from alternating benzo[1,2-b:4,5-b′]dithiophene (BDT) and benzotriazole backbone units. With a strong absorption profile spanning 450–600 nm in the visible light region, J52 effectively complements non-fullerene acceptors (NFAs) to achieve broad-spectrum light harvesting. Its well-balanced optoelectronic properties and compatibility with NFAs enable high-efficiency polymer solar cell performance. By combining good processability, favorable energy alignment, and stable device morphology, J52 is a valuable donor material for next-generation organic photovoltaic devices targeting efficient and sustainable solar energy conversion.
