DOI: 10.1002/aenm.202401597
Abstract: Developing non‐halogenated solvent‐processed organic solar cells (OSCs) demands precise control over the bulk‐heterojunction (BHJ) morphology of the photoactive layer. However, the limited solubility of halogen‐free solvents to photoactive materials hinders microstructure morphology fine‐tuning for boosting… read more here.

DOI: 10.1002/aenm.202500024
Abstract: Achieving commercial viability for organic solar cells (OSCs) requires non‐toxic, non‐halogenated solvent processing. However, poor solubility and suboptimal morphology of commonly used active layer materials have been limiting their non‐halogenated solvent applications for high‐performance OSCs.… read more here.
