Acceptor-donor-acceptor triads consisting of diketopyrrolopyrrole (DPP) or pyrrolopyrrole aza-BODIPY (PPAB) or both as acceptors and cyclopentadithiophene as a donor were rationally designed for near infrared (NIR) photovoltaics application. Among them, the PPAB-based triad exhibited the highest power conversion efficiency of 3.88% owing to the panchromatic absorption in the UV/vis/NIR regions.
受体-给体-受体三联体由二酮吡咯并吡咯（DPP）或吡咯并吡咯氮杂-BODIPY（PPAB）或两者作为受体和环戊二噻吩作为供体组成，用于近红外（NIR）光伏应用。其中，基于 PPAB 的三联体由于在 UV/可见/NIR 区域的全色吸收，表现出最高的功率转换效率为 3.88%。
