Abstract

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.

Endodontik NiTi Eğelerden Elde Edilen TiO2' nin Boya Duyarlı Güneş Pillerinde Kullanımının Araştırılması

Abstract

Artan enerji taleplerin karşılanmasında yenilenebilir enerji türleri açısından popüler olan fotovoltaik teknolojiler üzerine verim artırmaya yönelik çalışmalar yapılmaktadır. Boya duyarlı güneş pilleri yüksek altyapı maliyeti gerektirmeyen yapılar olduğundan verim artırmaya yönelik çalışmalar boya duyarlı güneş hücreleri (DSSC) üzerine yoğunlaşmıştır. DSSC’de ışığa duyarlı boya, TiO2 tabakasına tutundurulmaktadır. Kullanım ömrünü tamamlamış NiTi alaşımı endodontik eğeler, farklı asitler üzerinden çözeltiye alınıp metalik değerlerine ayrıştırılmış ve bu metalik değerlerden olan anataz fazında olduğu tespit edilen TiO2 ‘nin boya duyarlı güneş hücrelerinde kullanımına yönelik çalışmalar yapılmıştır. Çalışma kapsamında atık NiTi eğelerden elde edilen kontamine TiO2 ‘nin yapısı karakterize edilmiş ve N719 boya çözeltisinin yüzeye tutundurularak optik özellikleri araştırılmıştır. Boya duyarlı güneş hücrelerinde kullanılan N719 boya çözeltisi uygulanan geri kazanım anataz TiO2 tatbik edilmiş yüzeyle ile görünür bölge spektrumunda belirgin bir etkinlik göstermediği ortaya konulmuştur.
