High-Performance Organic Solar Cells from Non-Halogenated Solvents

Di Wang et al.

Summary: The study demonstrates that high-performance organic solar cells (OSCs) can be obtained from hot spin processing of different non-halogenated solvents, achieving the highest reported efficiency of OSCs so far. The phase evolution of ternary blends during solution-to-solid transition is found to be correlated to the substrate temperature, and optimal blend films can be secured in various non-halogenated solvents with elevated substrate temperature. As a result, high-performance OSCs with excellent power conversion efficiencies have been achieved in o-xylene, p-xylene, and toluene, respectively, representing the best-performing OSCs made from non-halogenated solvents to date.
