Abstract
The photovoltaic performance of DSSCs fabricated with different electrode thickness and different annealing temperature with the P25 $TiO_2$ and the Dyesol $TiO_2$ was measured. Thickness change of $TiO_2$ electrodes was measured using cross-sectional FE-SEM before and after annealing. Photovoltaic efficiencies of DSSCs were also measured by changing annealing temperature of platinum (Pt) paste on the counter electrode. Photovoltaic performances of DSSCs made with one layer of P25 (${\sim}20.4\;{\mu}m$) and one layer of Dyesol $TiO_2$ (${\sim}9.1\;{\mu}m$) annealed at $500^{\circ}C$ for 30 min. showed highest efficiencies of 3.8% and 5.8%, respectively.
