Abstract
- The solubility problem of conjugated polymers in nonhalogenated solvents limits the application of nonhalogenated solvents in Organic solar cells (OSCs). By combining with a hot spin‐coating process, efficient PM6:BTP‐BO‐4F:GS‐ISO ternary OSCs are prepared by employing o‐xylene as a solvent. After adding 10 wt% content of GS‐ISO to PM6:BTP‐BO‐4F, the surface morphology in the active layers is improved and the charge extraction, transport, and collection in OSCs are enhanced. Compared with the efficiency of PM6:BTP‐BO‐4F OSCs (16.25%), an efficiency of 18.63% is achieved for PM6:BTP‐BO‐4F:GS‐ISO ternary OSCs. Moreover, PM6:BTP‐BO‐4F:GS‐ISO ternary OSCs with an efficiency of 14.13% are prepared in air. The work provides a new strategy for preparing efficient and environmentally friendly OSCs using green solvents. [ABSTRACT FROM AUTHOR]
