Abstract
In this work, the three-dimensional of graphene oxide/Ba2VPbSe6 composites with cellulose (GB@C) have been successfully synthesized via a simple hydrothermal method and used as the counter electrodes (CEs) in dye-sensitized solar cells (DSSCs). The three-dimensional GB@C framework showed multiple benefits, such as high surface area, electrocatalytic ability, stability, and high-speed electron conduction, which can improve the conversion efficiency of DSSCs. The special properties and performances of various amounts of graphene oxide (10–30 wt%) as counter electrodes are presented. The highest photoelectric conversion efficiency (PCE) reached 9.47% with 20 wt% GB@C, which was higher than the pristine Pt CEs at the same conditions. Thus, we introduce a novel GB@C framework an alternative for CEs to improve the performance of DSSC cells.
