Abstract

To enhance the efficiency of a newly developing dye-sensitized solar cell (DSSC), Cu@C (7-20 nm) nanoparticles dispersed electrolyte has been studied. Experimentally, the efficiencies (η) of the DSSC are in the range of 2.70-4.09% with a short-circuit photocurrent density (J_sc) of 5.775-9.910 mA/cm². Interestingly, it is found that addition of 1% of Cu@C (7 nm) nanoparticles in the molten salt (1,2-dimethyl-3-propylimidazolium iodide (DMPIT)) conjugated electrolyte leads to an enhancement of 11% in the conversion efficiency (η) of 4.06%>. By XANES, about 17-32% of copper in the core of Cu@C are oxidized to Cu₂O (10-17%) and CuO (5-17%) in the molten salt in the electrolyte.
