| Abstract | Graphene quantum dots (GQDs)/PEDOT:PSS films exhibit the improved interfacial contact with substrate encouraging bettercharger transport in organic photovoltaics (OPVs). The GQDs/PEDOT:PSS films were successfully prepared by mixing ofGQDs and PEDOT:PSS under sonication. The mixtures were deposited on SnO2:F (FTO) substrate using a convective depositionsystem and characterized. Optical transmittance of the GQDs/PEDOT:PSS films reveals higher average value thanthat of the PEDOT:PSS films. Surface contact angles display similar decreasing trends for all films. For OPVs fabrication,GQDs/PEDOT:PSS films were used as a hole transporting layer in the OPV device. Power conversion e ciency (PCE) isenhanced to the maximum value of 1.71% for the GQDs/PEDOT:PSS film-based in comparison to the PEDOT:PSS film-based(1.14%). The enhancement is dominating correlation to the improved short-circuit current density and fill factor due to the hightransmittance and the improved interfacial contact, respectively. GQDs are not only improving interfacial contact on the FTOsubstrate but also full-filling coverage over the substrate. Therefore, GQDs are demonstrated as a potential additive material forPCE enhancement of OPVs. |
