Investigation of the Use of TiO2 Obtained from Endodontic NiTi Files in Dye-Sensitized Solar Cells
Öz
To meet the increasing energy demands, studies are carried out to increase the efficiency of photovoltaic technologies, which are popular in renewable energy types. Since dye-sensitized solar cells do not require high infrastructure costs, studies to increase efficiency have focused on dye-sensitized solar cells (DSSC). In DSSC, the photosensitive dye is attached to the TiO2 layer. Endodontic files of endodontic NiTi alloy, which have completed their service life, were taken into solution over different acids and separated into their metallic values. Studies were carried out using TiO2, which was found to be in the anatase phase, which is one of these metallic values, in dye-sensitized solar cells. Within the scope of the study, the structure of contaminated TiO2 obtained from waste NiTi files was characterized, and its optical properties were investigated by attaching N719 dye solution to the surface. It has been revealed that the N719 dye solution used in dye-sensitized solar cells does not show significant activity in the visible region spectrum with the recovered anatase TiO2 treated surface.
