DSSCs efficiency by thickness of TiO2 photoelectrode and thickness differences between two substrates studied. DSSCs is made of the doctor blade method and photoelectrode annealing temperature elevated in a different ways. In addition, cells efficiencies of according to the different thickness between TiO2 photoelectrode substrate and Pt counter electrode was measured. Efficiency of DSSCs made with TiO2 photoelectrode of 18 ㎛thickness and the gap difference between the substrate 28 ㎛shows a highest 4.805% efficiency.
