Dye-sensitized solar cells (DSSC) are among the interesting generations of solar cells that require further research to achieve industrial production. Current platinum (Pt) counter electrodes used in DSSCs is expensive and should be replaced by cheaper materials. In this study, we propose the tin-selenide (SnSe) material prepared on ITO substrates by the electrodeposition method as a Pt replacement. Our prepared materials demonstrated excellent electrocatalytic behavior and charge transport with iodide/triiodide electrolyte that is confirmed by cyclic voltammetry and electrochemical impedance spectroscopy. Our best DSSC reached efficiency of 4.9% that was slightly lower than the DSSC fabricated with Pt counter electrode. Therefore, our study shows that the low cost and earth-abundant SnSe prepared by the electrodeposition method is a suitable replacement for Pt in DSSCs.
