Co-Doping of Titanium Dioxide with Zinc and Nitrogen for Improvement of Dye Sensitized Solar Cell Performance
Abstract
Energy will be one of the major problems all over the world in coming decades, as the natural energy sources will be exhausted soon. Solar energy will be a best alternative energy sources to solve this problem. Different types of solar cells have been fabricated for solar energy conversion into electricity. In the present work, dye sensitized solar cell (DSSC) has been fabricated by co-doping of TiO2 with Zn (metal) and N (non-metal). Co-doped TiO2 semiconductor was prepared by sol-gel method and deposited on FTO glasses, which was sensitized with Rhodamine-B. This DSSC consists of a carbon as a counter electrode and iodide/triodide ion redox couple as electrolyte solution between the electrodes. The experimental results showed VOC=190 mV, iSC=0.0425 mA, ipp =0.0343 mA and Vpp =52.4 mV with fill factor (FF)=0.24 and power conversion efficiency of 0.032â„… under 60.0 mWcm-2 light intensity.
