Achieving 20% Toluene-Processed Binary Organic Solar Cells via Secondary Regulation of Donor Aggregation in Sequential Processing

Caption

·Isomeric molecules are introduced to fine-tune the secondary nucleation process of the donor underlayer.

·Binary organic solar cell processed with non-halogen solvent shows a champion efficiency of 20.0% (certified 19.7%).

·Mechanism of the film formation processes and the sequential processing community about solvent design rules are proposed.
