Layer-by-layer blade-coated organic solar cells with non-halogenated solvents and non-halogenated additive <i>via</i> adjusting morphology and crystallization

Abstract

Non-halogenated solvent additive DMN induces nucleation and crystal growth of Y6 molecules twice during the LBL blade-coating process, promoting the crystallization and nanoscale phase separation and leading to enhanced PCE of LBL blade-coated OSCs.
