The effects of these solvents on the morphology, charge mobility, and PSC device performance have been systematically studied. The general applicability of these non-halogenated solvents to diverse polymer/fullerene systems has also been demonstrated. © 2013 The Royal Society of Chemistry.[SDGs]SDG7Bulk heterojunction; Bulk-heterojunction (BHJ); Charge mobilities; Device performance; Environmentally friendly processing; Polymer solar cell (PSCs); Polymer Solar Cells; Power conversion efficiencies; Halogenation; Heterojunctions; Solar cells; Polymers; electronic equipment; energy efficiency; fullerene; halogen; performance assessment; solar power; solar radiation; solventjournal article10.1039/c3ee41915k2-s2.0-84886035900
