Improvement of dispersibility and film formability of TiO2 nanoparticles by surfactant modification
We have focused on effect of rutile type TiO 2 to ETL (electron transport layers) of hybrid perovskite solar cells. The rutile type TiO 2 was synthesized by a hydrothermal method using a water-soluble titanium complex as a titanium source. In order to improve dispersibility, rutile type TiO 2 was modified by various types of dispersants. When Triton X was used as a dispersant, dispersibility of rutile type TiO 2 was improved, and FTO glass could be uniformly covered. Using this substrate, perovskite solar cell was fabricated. Energy conversion efficiency of the cell was 10.42 %.
