Abstract
U radu je ispitivana efikasnost fotonaponskih ćelija pripravljenih na osnovi nanokristaličnog TiO 2 , uz različitu viskoznost paste i debljine nanesenog tankog sloja TiO 2 na staklu. Kompaktnost sloja provjeravana je optičkim mikroskopom, a njegova mehanička otpornost provjeravana je metalnom špatulom. Na nanokristalične TiO 2 filmove naneseno je fotoosjetljivo organsko bojilo ekstrahirano iz cvijeta hibiskusa. Na četiri staklene pločice nanesen je ugljični sloj pomoću plamena, a na ostale četiri pomoću grafitnog spreja. Inducirani napon je mjeren sedam dana te je na osnovi dobivenih vrijednosti zaključeno o efikasnosti fotonaponskih ćelija. Najveću vrijednost induciranog fotonapona dale su fotoćelije pripravljene s tankim slojem nanokristaličnog TiO 2 , iz paste manje viskoznosti, zagrijavanjem u laboratorijskoj peći od sobne temperature do 400 °C uz brzinu zagrijavanja od 10 °Cmin -1 . Grafitni sloj nanesen sprejem pokazao se kao efikasniji u odnosu na ugljični sloj nanesen plamenom, tj. ćelije s ugljičnim slojem, dobivene raspršivanjem pokazale su više vrijednosti fotoinduciranog napona.
Abstract (english)
This paper investigated the photovoltaic cells efficiency based on nanocrystalline TiO 2 , with different viscosity of paste and thickness of thin TiO 2 layer applied to glass. The compactness of the layer was checked by an optical microscope, and its mechanical resistance was checked with a metal spatula. On the nanocrystalline TiO 2 films, a photosensitive organic dye was filed, extracted from the hibiscus flower. On four glass tiles, the carbon layer was coated with flame, and the other four carbon layers were sprayed with graphite spray. The induced voltage was measured for seven days and based on the obtained values, the efficiency of photovoltaic cells was determined. The highest value of the induced voltage had photocells prepared with a thin layer of nanocrystalline TiO 2 , from a paste of less viscosity, by, heating in a laboratory oven from room temperature to 400 °C with a warming rate 10 °C min -1 . The graphite coating applied by the spray proved to be more efficient with respect to the carbon coating applied by the candle, i.e. the carbon-coated cell obtained by spraying, showed more value of the photoinduced voltage.
