Projekti eesmärk on selgitada välja valguse poolt genereeritud laengukandjate rekombinatsioonikanalid, mis vähendavad päikesepatareide efektiivsust, ja leida võimalused selliste rekombinatsioonikanalite mõju vähendamiseks. Seejuures selgitatakse välja defektide olemasolu päikesepatareide materjalides, defektide osa valguse poolt genereeritud laengukandjate rekombinatsioonis ja laengulõksude paiknemine päikespatareide materjalides. Uuritakse uute tehnoloogiliste meetodite rakendusvõimalusi kvaliteetsemate päikesepatareide materjalide valmistamisel. Töö oodatavaks tulemuseks on ökonoomsete päikesepatareide energiamuundamise efektiivsuse suurenemine.
The goal of the project is to reveal the recombination channels for light-induced charge carriers in solar cell materials, and establish possible routes to suppress the detrimental effect of those recombination paths. A comprehensive set of techniques will be applied (i) to reveal the presence of different types of defects in various absorbers, (ii) to determine the role of defects in the parasitic recombination of photo-induced charge carriers, (iii) to localize the trapping centers in absorber materials, and (iv) to evaluate application perspectives of new methods for preparation of solar cell materials of higher quality. Increase in energy conversion efficiency of low-cost solar cells is expected as a result of the studies.
