- Abstract
- A mesoporous TiO2 photo-electrode for dye-sensitized solar cells (DSSCs) was fabricated
by an electrospray method using a solution of dispersed TiO2 nanocrystals (P25). A mesoporous TiO2
disk has a larger surface area than P25. The sub micrometer-sized TiO2 disk promotes light scattering,
thereby increasing the photocurrent conversion efficiency. However, the electrosprayed TiO2
electrodes have many pores and disconnected electron pathways. Thus, we investigated the enhanced
electrical contact of an electrosprayed TiO2 electrode using a hot-pressing process and a titanium
tetrachloride (TiCl4) treatment process. After optimizing the post-treatment process of an
electrosprayed TiO2 electrode, the cell shows conversion efficiency up to 6% at standard sunlight of
AM 1.5.
