Enhancing Input Energy in Dye-sensitized Solar Cell (DSSC) by Using Swift Heavy Ion (SHI) Irradiated ITO

Dye-sensitize solar cell (DSSC) is the third generation solar cell and has efficiency around 11%. It harnesses sun light by photo-sensitive dyes which are adhered on the porous surface of the wide band gap oxide material. To increase efficiency of DSSC, it is necessary to increase its input power and keeping such aim Indium-Tin-Oxide (ITO) substrate of photo anode is irradiated by Swift heavy ion (SHI) irradiation. Irradiated ITO is characterized by UV-Vis and Four-Probe method. UV-Vis transmittance mode spectra shows that transmittance increases 5 to10% and Sheet resistance also increases but in acceptable limit with SHI irradiation. Therefore SHI irradiation is good tool to increase the input power of the DSSC by modifying ITO substrate.
