In-Situ Crosslinked Matrix enables Efficient and Mechanically Robust Organic Solar Cells with Frozen Nano-Morphology and Superior Deformability

An in-situ cross-linkable monomer is carefully developed into blend films to finely manipulate the molecular packing, crystallization and nanomorphology during film formation. As a result, stabilized PCEs of 19.84% for the rigid device and 18.32% for flexible organic solar cells are achieved.
