文摘

Two-dimensional (2D) conjugated side-chain polymer can extend π-conjugation length. 2D conjugated type polymer features a low HOMO energy level for a high open-circuit voltage (VOC). PQCT-BT exhibited the best power conversion efficiency (PCE) of 2.2% and the open-circuit voltage (VOC) was 0.92 V.
