Eco-friendly Solvent-Processed High-Performance Indoor Photovoltaics made of New Conjugated Terpolymers |
| 초록 |
The conjugated random terpolymers, PJ-25, PJ-50, and PJ-75 were successfully synthesized from three different monomers. Fluorine-substituted benzotriazole (2F-BTA) was incorporated into BDT-T-Cl and BDD based alternating copolymer PM7 as a third monomeric unit. Outdoor photovoltaic (PV) cells (AM 1.5G) based on the PJ-50:IT-4F blend showed high power conversion efficiency (PCE) of 11.34%. In addition, the selected polymer donor of PJ-50 was also employed for indoor PV (IPV) cells and was blended with non-fullerene acceptors, which have different absorption range. Among them, the PJ-50:IT-4F-based IPV device had the highest PCE of 17.41% with a Jsc of 54.75 μA cm-2 and an FF of 0.77 under a 160 μW cm-2 LED light. The terpolymer introduced in this study can be regarded as a promising material for the fabrication of outdoor PV and IPV cells with excellent performance involving the use of an eco-friendly solvent. |
