Abstract:
anic solar cell (OPV) is one of the hottest frontiers in chemistry and materials science. China has been leading this hot frontier, and Chinese researchers have made great contribution to this research field. We proposed a novel concept — fused-ring electron acceptor (FREA) , established a brand-new, high-performance nonfullerene acceptor system, and invented star molecule ITIC. These FREAs show some advantages: (1) they have high electron mobility similar to those of fullerenes; (2) they exhibit strong and broad absorption, especially in the 700 – 1000 nm range, and can match with wide-bandgap donor materials to plementary absorption; (3) their energy level can be tuned and thus they match with various high-performance electron donors; (4) their crystallinity and film morphology can be tuned; (5) their synthesis is easy to scale up. Our original and pioneering work has rec
