The Effect of Radiation on the Optical properties of TiO2 thin films as Solar Cell Application

This study investigates the effect of Alpha radiation on dye_sensitized solar cell. The DSSC was manufactured using a TiO2 thin-layer anode, a conductive glass FTO (Fluorine-Doped Tin Oxide) glass substrate, a counter electrode that was deposited with aluminium (Al)on the FTO glass, and two dyes (a natural dye, blackberry, and a synthetic dye, methylene blue). It was detected that irradiation is positive, as we found that the longer the irradiation time, the higher the efficiency. This research studied the J-V curve and UV-Vis. of the cell. The UV-Vis results showed that. the energy band gap decreases with increasing irradiation and the energy gaps were (3.01,2.90 and 2.77) eV for (st,30min,60min) samples respectively. The best result appeared for the cell using the synthetic dye methylene blue; the cell parameters were open circuit voltage (0.69) volt, Jsc(5.85mA/cm2), FF at (0.15), and efficiency 1℅. The results showed that DSSC, which uses radiation, is a promising method for future research.
