Notes:
To enhance the electrical conductivity of the electrolyte in a newly-developeddye-sensitized solar cell (DSSC), the Cu@C (metallic copper core in the carbon shell) nanoparticlesdispersed in a room temperature ionic liquid (RTIL) (e.g., [bmin][BF6]) has been studied in thepresent work. By the pulsed-field gradient spin-echo NMR method, the self-diffusion coefficientsof cations and anions in the RTIL have been determined. The self-diffusion coefficient of cationsis increased by 40% at 300 K. It is also found that the electrical conductivity of the Cu@Cdispersed (0.08%) RTIL is increased by 30% (1.96→2.38 ms/cm). It seems that that the nanosizeCu@C dispersed RTIL is a very effective electrolyte especially used in the DSSCs
