The presence of P-CQDs P3HT:PCBM layer (1 vol% of P-CQDs) enhanced photon harvesting in the UV region and emitting visible light, the PCE was increased from 2.19% to 2.48% and champion device provided a FF of 55.34%. The incorporation of P-CQDs leads to effective photons harvesting ability and collection/transport of charge carriers. The optical absorption and crystallinity of photoactive layer improved with the incorporation of P-CQDs. The larger grain size distribution were obtained with P-CQDs additive helping to better charge extraction. © 2024 Elsevier B.V.eninfo:eu-repo/semantics/closedAccessAdditive engineeringCarbon quantum dotsHeteroatom dopingOrganic solar cellP3HT:PCBMAdditivesCarbonCell engineeringCrystallinityGrain size and shapeLight absorptionNanocrystalsPhosphorusPhotonsSemiconductor quantum dotsAdditive engineeringCarbon quantum dotsDoped carbonsHeteroatom dopingHeteroatomsLayer 1P3HT:PCBMPerformancePerformance enhancementsPhosphorus-dopedOrganic solar cellsArticle10.1016/j.cplett.2024.1413002-s2.0-85191652790
