Polymeric Acceptors Containing the Same Building Block with Polymer Donors Enhanced Interfacial Compatibility, Mechanical Robustness, and Efficiency of All-Polymer Solar Cells |
초록 |
Recently, polymer acceptors (PAs) consisting of small molecule acceptors (SMAs) with strong light absorption have been proposed to enhance the power conversion efficiency of all polymer solar cells (all-PSCs). However, polymerization of NFSMAs often reduces entropy of mixing in PSC blends and prevents the formation of intermixed blend domains required for efficient charge generation and morphological stability. One approach to increase compatibility in these systems is to design PAs that contain the same building blocks as their polymer donor (PD) counterparts. Here we report a series of SMA-based PAs [P(BDT2BOY5-X)], by copolymerizing SMA with benzodithiophene. All-PSC blends composed of PBDB-T PD and P(BDT2BOY5-X) PA show enhanced molecular compatibility, resulting in excellent morphological, mechanical, and electrical properties. |
