摘要： The performance of dye sensitized solar cell (DSSC) is largely dependent on efficient electron reclamation from outer circuit to reduce the oxidized redox shuttle (electrolyte). The current transparent conducting oxide (TCO) glass substrates and platinum (Pt) metal as essential components of counter electrodes though efficient are very expensive which restrict commercialization of this technology. Furthermore, the sluggish catalytic activity of indium tin oxide (ITO) or fluorine doped tin oxide (FTO) play no role in electron reclamation. In this study, commercially available cost effective tin-silver-copper (Sn-Ag-Cu) ternary composite past has been investigated as potential replacement for FTO coating and Pt catalyst to work in conjunction with counter electrode of dye sensitized solar cell. Scanning electron microscopy (SEM) has been utilized to examine the morphology of as received paste. Electrochemical analysis such as cyclic voltammetery (CV) and electron impedance spectroscopy (EIS) have been employed to investigate the catalytic activity and electron kinetics respectively. Finally, current-voltage characteristics have been investigated using IVT 2600 solar simulator. The Sn:Ag:Cu composite exhibited remarkable catalytic properties which in turn lead to impressive over all photo energy conversion efficiency. The measured conversion efficiency was 6.78% which is almost 86% equivalent to DSSCs containing Pt has catalyst on FTO.
