Effect of Platinum loaded Multi Walled Carbon Nanotube Counter Electrode on Dye Sensitized Solar Cell
Dye Sensitized solar cells were the Photovoltaic cell that converts visible light energy into electrical energy. DSSC can be used to produce electrical energy in a wide range of light conditions. They can be used indoor as well as outdoor. DSSC convert both artificial and natural light into energy that can be used in electronic devices. Dye Sensitized solar cells are able to provide energy with a more affordable cost of fabrication and the production than solar cells that are made from crystalline silicon. Counter electrode also known as Auxiliary electrode. It is made from fluorine-doped tin oxide (FTO) glass which is coated with Catalyst layer to increase electron transfer rate. In order to obtained enhanced energy conversion rate of DSSC, Multi-Walled carbon nanotubes (MWCNTs) were used in counter electrode. Platinum counter electrode and Platinum-Multi-Walled CNT counter electrode were fabricated. All these counter electrodes were fabricated on FTO glasses. The performance of solar cell was measured with the help of solar light simulator. The Structure of counter electrodes were studied by Scanning Electron Microscopy images. Results shows that enhanced efficiency was obtained by using the Pt-MWCNT Counter Electrode. Keywords—DSSC, Counter Electrode, Pt, MWCNT, Efficiency
