The structural and morphological characterization results showed that the optical absorption and film crystallinity can be easily enhanced by B-CQDs additive in P3HT:PCBM solution. Additionally, with the improved crystallinity of P3HT, the effective interchain interaction and phase separation in photoactive layer were achieved. As a result,-50% improving of FF of the device with 5 vol% of B-CQDs additive was determined. Thanks to improved photovoltaic characteristics, best performing device showed a power conversion efficiency of 2.7% (with-50% improve-ment). This report shows that the addition of optimized vol% of B-CQDs into the photoactive blend strongly improves the absorption and leads to achieve efficient charge separation and transport in OSCs.eninfo:eu-repo/semantics/closedAccessB-CQDsOrganic solar cellsOptical propertiesCrystallinityCARBON QUANTUM DOTSArticle10.1016/j.mee.2020.1114652-s2.0-85093686205
