PBDB-T-2F is a high-performance donor polymer from the PBDB-T family, widely recognized for its outstanding efficiency in non-fullerene polymer solar cells (NF-PSCs). Incorporating two fluorine atoms into each thiophene unit of the BDT side chains tunes HOMO/LUMO energy levels and promotes favorable morphology. When paired with ITIC-2F as the acceptor, PBDB-T-2F achieves power conversion efficiencies exceeding 13% due to controlled phase separation and high domain purity. Moreover, certified efficiencies up to 14.9% have been demonstrated in single-junction NF-PSCs using PBDB-T-2F with Y6, highlighting its importance in next-generation organic photovoltaic research.
