Abstract:

The interest in the dye sensitized solar cell is due to its low cost, simple preparation techniques and benign effect on the environment. Thin film of TiO2 deposited on FTO (Fluorine doped Tin Oxide) acts as one electrodes, platinum coated FTO acts as the other electrode and eosin B solution acts as the sensitizer. Lithium iodide, iodine in acetonitrile solution is used as the electrolyte. It is noted that an efficiency of 7.4% was observed for a cell with Intensity 70 lux. Also the open circuit voltage of 0.5V, short circuit current of 150µA and a fill factor of 0.68 were observed for the cell of area 1X1 cm 2. The experimental model is checked with theoretical model using MATLAB software. It is noted that the simulated values follow a pattern which closely resembles the actual values of the experiment. The effect of the aging process on the overall performance of the device was analyzed by means of electrochemical impedance spectroscopy. The results shows that the electrolyte-TiO2 capacitance of 20 µF (parallel) and the resistance of 14.74 k ohms (parallel) in series with the platinum resistance of 25.58 ohms.
