단일벽 탄소나노튜브를 이용한 염료감응형 태양전지의 광전지적 성능 향상에 관한 연구

Abstract

Dye-sensitized solar cells (DSSCs) was fabricated with nanocrystalline TiO2 film electrode on FTO glass, N719 dye, electrolytes (or CsSnI3), and counter Pt electrode by incorporating with single-walled carbon nanotubes (SWNTs). SWNTs were combined with TiO2 film, CsSnI3, Pt electrode, separately, and SWNT-containing cell was compared with 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.
