Non-fullerene acceptors for commercially viable organic photovoltaics — •Derya Baran — King Abdullah University of Science and Technology (KAUST), Thuwal, Saudi Arabia

The commercialization of OPV requires the availability of inexpensive materials in large quantities, such as poly(3-hexylthiophene) (P3HT). P3HT is readily scalable via flow or micro-reactor synthesis, even using green solvents, whilst retaining a high degree of control over molecular weight and regio-regularity. However, it has a limited open-circuit voltage (Voc), short-circuit current (Jsc) and stability in photovoltaic devices when fullerene derivatives are used as acceptors. This talk will focus on the alternative small molecule non-fullerene acceptors that lead to the highest power conversion efficiencies with P3HT donor. The devices show excellent stability in air and are promising for commercializing OPV in the near future.
