Abstract
All-polymer organic photovoltaics (OPVs) are highly promising for indoor light energy harvesting due to their tunable optoelectronic properties and compatibility with large-area solution processing. In this study, we synthesized a novel NDI-based polymer acceptor, P(NDI2OD-Se-Th 0.8), incorporating a selenopheno[3,2-b]thiophene backbone via Stille polymerization. The resulting polymer exhibits a medium optical bandgap and was blended with a commercial donor polymer, PBDB-T, to form a bulk heterojunction (BHJ) structure. By adjusting the Se-Th content to 80%, the acceptor achieved favorable absorption characteristics under indoor light, stable film morphology, and good phase separation.
