摘要：

Solution-processable functionalized graphene oxide (SPFGO) thin films as the hole transport layer in organic photovoltaics (OPVs) are fabricated. The performance of the device has been improved by the incorporation of SPFGO. The best results of the open-circuit voltage (V-oc), short-circuit current density (J(sc)), fill factor (FF) and power conversion efficiency (POE) were 0.57 V, 7.7 mA/cm(2) 0.65, and 2.90%, respectively, which are achieved when the thickness of SPFGO film is 3 nm. The dramatic increase in the POE of OPVs are comparable to those devices fabricated with PEDOT:PSS as the hole transport layers. Therefore, we suggest that SPFGO thin films could be a promising solution-processable alternative to PEDOT:PSS as the effective hole transport layers (HTLs) in OPV devices.
