Abstract
Nano-porous TiO2 film as a photoelectrode plays an
important role in dye-sensitized solar cell. The TiO2 film is generally
prepared from precursor paste including TiO2 nano particles by heating.
Additives in the precursor paste and "bilayer" compositions of TiO2
films were studied. The reflectance of TiO2 film prepared from
nitric-acid added paste was higher than that from acetylacetone-added paste
over visible light region. Energy conversion efficiency of cell using the
former film as single layer electrode is low. However, in the case of
bilayer, electrode consisting of film prepared from nitric-acid added paste
on the substrate side showed much increase of efficiency compared with
acetylacetone-added film. It is considered that nitric acid improves the
electric contact of TiO2 layers.
