Anatase (TiO2) thin layers for solar energy conversion
This paper describes the possibilities of obtaining nanostructured TiO2 using Spray Pyrolysis Deposition and its application in a solid state solar cell (FTO/ TiO2 In2S3/ CuSbS2/ graphite). Nanostructured TiO2 films are deposited from ethanolic solution of titanium (IV) isopropoxid, (TTIP, 99.99%, Sigma-AIdrich), and acetilacetonate, (AcAc, 99+%, Aldrich); two parameters are proposed for investigation: the annealing duration in air at 500degC, tTT (h), and the number of sprayed sequences, No.p.c.. The layers are characterised by XRD, AFM, Raman Spectroscopy, UV-VIS Spectroscopy and the cells by current-voltage measurement in dark and under illumination. It was found that annealing and the spraying time structure can be o a method of tailoring the TiO2 thin films properties and can influence the photovoltaic response of the cells. The best response was obtained for the cell obtained with TiO2 thin films deposited with 20 number of sprayed sequences and 6 h of annealing in air at 500degC, for which the open circuit voltage is Voc = 210 mV, the short circuit current is IIc = 8.13-10-2 mA, the values of the maximal power is defined by Vmax = 117 mV and Imax = 4.64O2ldr102 mA, corresponding to a fill factor FF = 0.318.
