Some Features of Dye-sensitized Solar Cell Combining with Single-walled Carbon Nanotubes

Abstract

A dye-sensitized solar cell (DSSC) was fabricated with a nanocrystalline TiO2 film electrode on FTO glass, N719 dye, electrolytes (or CsSnI3), and counter Pt electrode by incorporating it with single-walled carbon nanotubes (SWNTs). SWNTs were combined with TiO2 film, CsSnI3, Pt electrode, separately, and the SWNT-containing cell was compared with a pristine cell in cell performance. We also examined the performance change by pressing TiO2 film, during cell fabrication, inside a high pressure chamber. Mostly, the change of conversion efficiency was compared for each cell, and an atomic force microscopy data were suggested to explain our results.
