Abstract
Safer Ink Systems In article number 2100567, Richard Swartwout and co-workers demonstrated the coating performance of their new, safer solvent ink mixture with an effective permissible exposure limit 10x higher than traditional DMF/DMSO ink systems. Regulatory requirements limit exposure to solvent vapors generated from ink-based coating processes. For perovskite photovoltaics, this requires new ink formulations that exclude traditionally hazardous solvents while simultaneously coating uniformly at scale.
