Synthesis and Investigation of Metals Oxide Pastes Used as Semiconductors Electrode for Dye-sensitized Solar Cells

The aim of this research is to prepare some of metal oxides pastes to be used as semi-conductors electrode to manufacture of solar cells devices (third generation). The efficiency of these cells were tested by using these pastes to determine the response and susceptibility of these pastes for adsorbing of photosensitive pigments on their surfaces and pores, Three types of metal oxides such as Titanium oxide, Zinc oxide and Aluminium oxide, were prepared in this research. These pastes were identified by measuring UV-visible spectra and also by microscope instrument. The experiments which have been demonstrated approved the susceptibility and adsorption of these pastes to the photosensitive dyes on their surface and gave conversion efficiency up to 1.64%. In this research, a comparison was made between the pastes that were prepared in laboratory and the imported commercial paste in terms of efficiency.
