Study on Ternary Blend Organic Solar Cells Based on Multiple Non-fullerene Acceptors

In recent years, non-fullerene acceptor materials for organic solar cells ( OSCs ) have attracted much attention. Among them, ITIC, Y6 and perylene diimide PDI been widely studied because of their easy structure regulation. The application development ITIC its derivatives, Y6, derivatives in ternary blend are reviewed detail. This work focuses on the molecular optimization method selection third component materials. At present, efficiency has exceeded 18%, but relationship between photovoltaic performance needs further exploration. Optimizing synthesis route is still an important research direction this field.
