Efficient Ternary Organic Solar Cells (>14%) Enabled By Non-Fullerene Acceptors

Abstract

Organic Solar Cells (OSCs) fabricated from a ternary active layer, comprised of a mixture of either two electron donors and one acceptor or one donor and two acceptors, are presently at the vanguard of competitive OSCs affording an increased PCE when compared to binary counterparts.In this presentation, we´ll show our last work in ternary OSCs using two small molecule donors or two electron acceptors reaching efficiencies as high as 14%.References Privado, P.
