Effect of Synthetic Quartz Nanoparticle-Supported Counter Electrode on Dye-Sensitized Solar Cell

We fabricated dye-sensitized solar cells (DSSCs) with synthetic quartz nanoparticle (SQNP)-supported Pt/fluorine doped tin oxide counter electrodes to utilize an adsorptive capacity of synthetic quartz. The amperage of I3− reduction was 1.6 times higher with SQNP than that without SQNP. SQNP also im...

Description
Summary:We fabricated dye-sensitized solar cells (DSSCs) with synthetic quartz nanoparticle (SQNP)-supported Pt/fluorine doped tin oxide counter electrodes to utilize an adsorptive capacity of synthetic quartz. The amperage of I3− reduction was 1.6 times higher with SQNP than that without SQNP. SQNP also improved the photocurrent density-voltage characteristics and the incident photon to current conversion efficiency spectra in the visible region. These suggest that SQNP enhances the I3− reduction activity on the counter electrode and the electron transfer to the photoanode. The SQNP-supported counter electrode is expected to be useful to raise the efficiency of a DSSC.
