In summary, we tried to boost the thermal stability of PSCs based on Y-series acceptors Y5-F-Br by polymerizing Y5-F-Br obtaining PFA1, and establish a precise correlation between the molecular structure and device thermal stability. Compared to the short-chain Y5-F-Br acceptor, the long-chain PFA1 acceptor may be entangled with the long-chain PTzBI-oF donor to form a similar “molecular lock” structure, which may effectively enhance the thermal stability of the PSCs at elevated temperatures.

Record-holding polymer solar cells (PSCs) composed of polymer donors and Y-series non-fullerene small molecule acceptors have reached the efficiency threshold for commercialization, but this type of PSCs is often difficult to work continuously and stably at high temperatures close to 100 °C, limiting its outdoor application. Therefore, in this work, we tried to boost the thermal stability of PSCs based on Y-series acceptors Y5-F-Br by polymerizing Y5-F-Br obtaining PFA1, and establish a precise correlation between the molecular structure and d...
