Abstract

Istražena su svojstva nanočestica TiO2 i TiO2 dopiran s atomima rijetkih zemlji (Sm i Ho) za primjenu u fotonaponskim ćelijama. Elektronskom mikroskopijom i Ramanovom spektroskopijom analizirana je morfologija i struktura pripremljenih materijala, a UV-Vis spektroskopijom optička svojstva tih materijala u formi tankih filmova. Dobiveni slojevi su integrirani u solarne ćelije s organskom bojom te je testirana njihova efikasnost mjerenjem strujnonaponske karakteristike upotrebom solarnog simulatora. Dobivena je nešto manja efikasnost solarnih ćelija s organskom bojom (eng. Dye-sensitized solar cells, skraćeno DSSC) na dopiranim podlogama TiO2 u odnosu na DSSC na podlogama čistog TiO2.

Abstract (english)

The properties of TiO2 nanoparticles and rare earth (Sm and Ho) doped TiO2 nanoparticles have been investigated for application in solar cells. Electron microscopy and Raman spectroscopy were used for morphological and structural characterization and UV-Vis spectroscopy for the optical properties of the prepared TiO2 thin films. The Dye-sensitized solar cells (DSSC) were assembled with the prepared TiO2 thin films, and their efficiency was tested with the solar simulators. The DSSC with the doped TiO2 layers had lower efficiency than the ones with undoped TiO2 layers.
