Abstract
U radu je ispitivana aktivnost solarnih ćelija s fotoosjetljivim bojilom (DSSC) na bazi nanokristaličnog cink (II) oksida na način da je fotoinducirani napon ćelija mjeren pri umjetnom osvjetljenju i pri sunčevoj svjetlosti tijekom 10 dana. Pasta nanokristaličnog ZnO pripremljena je uobičajenim postupkom bez primjene kiseline. Konzinstencija paste podešena je dodatkom etilnog alkohola i sredstva za poboljšanje kvašenja, neionskog disperganta Triton-X 100. Cilj je bio dobiti kompaktan porozni sloj koji dobro prijanja na površinu vodljivog stakalca. Stakalca s nanesenim slojem nanokristaličnog ZnO termički su obrađena te su nakon obrade uronjena u pripremljenu otopinu antocijanina ekstrahiranog iz suhog cvijeta hibiskusa, kojem je određen UV-Vis spektrogram. Na vodljivu stranu stakalaca za katode solarnih ćelija nanesen je sloj grafita metodom prskanja te su potom katode sušene radi uklanjanja organskog otapala. Stakalca s nanesenim tankim slojem nanočestica ZnO te stakalca s nanesenim slojem grafita proučavana su digitalnim mikroskopom prije i poslije termičke obrade. U fotoćelije su dodavani komercijalni elektrolit te elektroliti pripravljeni na osnovi I 2 i KI otopljenih u etilen-glikolu i tetraetilen-glikolu. Rezultati pokazuju visoku aktivnost fotoćelija i uz umjetno osvjetljenje i na sunčevoj svjetlosti, bez potrebe za dodatkom nove količine elektrolita i do 9 dana.
Abstract (english)
In this paper, the activity of dye-sensitized solar cells (DSSCs) based on nanocrystalline zinc(II) oxide was analyzed by measuring the photo-induced voltage of the cells under artificial lighting and under sunlight over a period of 10 days. The nanocrystalline ZnO paste was prepared by the usual process without the use of acid. The consistency of the paste was adjusted by the addition of ethyl alcohol and a wetting agent, the nonionic dispersion of Triton-X 100. The goal was to obtain a compact porous layer that adheres well to the surface of conductive glass. The conductive side of solar cells with an applied layer of nanocrystalline ZnO was thermally treated and, after the treatment, was immersed in a prepared solution of anthocyanin extracted from a dry hibiscus flower, for which the UV-Vis spectrogram was determined. A layer of graphite was applied to the conductive side of solar cells using the spraying method, and then the cathodes were dried to remove the organic solvent. Glasses with a thin layer of ZnO nanoparticles and glasses with a graphite layer were analyzed with a digital microscope before and after the thermal processing. Commercial electrolytes and electrolytes prepared on the basis of I 2 and KI dissolved in ethylene glycol and tetraethylene glycol were added to the photocells. The results show a high activity of the photocells both with artificial lighting and in the sunlight, without the need to add a new amount of electrolyte for up to 9 days.
