Abstract: | |
Activated carbon prepared by the carbonization of wood of Choerospondias axillaris (Lapsi) seed-stones and Alnus nepalensis (Utis) plant have been used as novel catalysts for reduction of tri-iodide ions in dye-sensitized solar cells (DSCs). The X-rays diffraction (XRD) and Raman spectroscopy of the activated carbons revealed that the carbonaceous materials contain amorphous and graphitic forms of carbon. The DSCs were tested in natural sunlight. The DSCs with counter electrodes (CEs) based on activated carbon of Lapsi seed-stones and Utis yielded efficiencies of 0.94 % and 1.12 %, respectively compared with 3.24 % of efficiency from the DSC with the CE based on commercially available graphite based carbon composite from Solaronix. |
