Abstract

Acceptor alloys based on n-type small molecular and fullerene derivatives are used to fabricate the ternary solar cell. The highest performance of optimized ternary device is 10.4%, which is the highest efficiency for one donor/two acceptors-based ternary systems. Three important parameters, J<sub>SC</sub> , V<sub>OC</sub> , and FF, of the optimized ternary device are all higher than the binary reference devices.
