Abstract

The artificial nano-clay powder was newly examined as a gelator of electrolyte of quasi-solid-state dye-sensitized solar cell (DSSC). The size of clay has two main distributions with 1.4 nm and 20 nm in diameter which are confirmed by STEM observation. The gelation point was determined by using Rheometer. The gel state maintained with more than 5wt% nano-clay in the acetonitrile based solvent. The quasi-solid-state DSSC with nano-clay electrolyte (10 wt%) was successfully showed a high photoelectric conversion efficiency of 10.3%, which is equivalent to that using a liquid electrolyte.
