Sprey metodu kullanılarak üretilen boya ile hassaslaştırılmış güneş pillerinin incelenmesi

In this thesis, we investigated the efficiency and maximum power of the dye-sensitized solar cell (DSSC) produced with the aid of spray pyrolysis method in the voltage range of 0-0.7 V. The fabrication of the cell contains 3 parts. (I) Deposition of Indium Tin Oxide (ITO) thin film on soda lime glass was carried out by DC magnetron reactive sputtering technique at 100 watt using an ITO ceramic target (In2O3:SnO2, 90:10 wt%) in argon atmosphere at room temperature. Then, the ITO film prepared was annealed at different temperature and time and the best annealing ambient was observed to be 400 °C for 2 h. The film produced was analyzed by means of X?ray diffractometer, ultraviolet visible spectrometer and atomic force microscopy investigations. (II) Titanium dioxide film (TiO2) was deposited on the ITO surface of glass soda lime by spray pyrolysis method after the best annealing environment was determined for the fabrication of the TiO2 thin film. Scanning Electron Microscopy (SEM), X?ray diffractometer (XRD), atomic force microscopy (AFM) and ultra-violet spectrometer (Uv-Vis) measurements were performed for the TiO2 film characterization. (III) Coating of the platinum (Pt) layer on ITO surface of soda lime glass was performed by DC magnetron reactive sputtering technique at 100 watt using a target composed of 90 wt% Pt in argon atmosphere at room temperature. This sandwich system was filled by electrolyte liquid called as iodide/tri-iodide ( ) of which the platinum layer was used to be the catalyst for the regeneration. Additionally, current-voltage measurement of the DSSC prepared was conducted under an illumination of 1kW/m2 and active area of 4cm2. The efficiency and maximum power of the cell are determined from Fill Factor. The results show that the former was found to be about 5.05 % when the maximum power was observed to be about 20.1mW. According to the results obtained, the dye-sensitized solar cell might be used as alternative energy source.
