▎ 摘　　要

This work is concerned with the utilization of silver doped reduced graphene oxide (Ag-rGO) films as counter electrode in a dye-sensitized solar cell (DSSC). The effect of annealing temperature of Ag-rGO on the properties of Ag-rGO and performance parameters of the device has been investigated. The annealing temperature has been varied from 350 degrees C to 400 degrees C at 10 degrees C interval. The DSSC utilizing Ag-rGO annealed at 350 degrees C demonstrated the highest eta of 1.302%, respectively due to the smallest charge transfer resistance at the interface of electrolyte/ Ag-rGO counter electrode. The efficiency has been improved by utilizing the Ag-rGO counter electrode that underwent annealing treatment. The performance and electrochemical stability test reveal that the DSSC utilizing free-platinum electrode that is Ag-rGO can last within one week time.
