摘要
All-polymer solar cells(all-PSCs)have significantly improved long-term stability and mechanical stretchability.The power conversion efficiency(PCE)of all-PSCs has been rapidly improved from∼1%to now over∼17%,driven by rational molecular design,blend morphology optimization,and device engineering.However,most all-PSCs are generally processed with halogenated solvents,hazardous for human health and the global environment.Achieving high-performance all-PSCs with halogen-free solvent processing remains a challenge.This feature article presents recent advances in green-solvent-processable all-PSCs from the material design and morphological control perspective,and further reviews progress in using more environmentally friendly solvents(i.e.,water or alcohol)to achieve genuinely sustainable and environmentally friendly manufacturing all-PSCs.Finally,we provide an outlook on the challenges and opportunities for large-scale manufacturing of green-solvent-processable all-PSCs.
