Tin oxide is a promising candidate for the replacement of titanium dioxide in dye-sensitized solar cells (DSSCs), due to its excellent electron transport properties. The performance of TiO2-based DSSCs can be improved either by modifying the morphology of SnO2 nanostructures, or by doping. Here, we investigate the influence of different dopants (Mg, Zn, and Ag) to SnO2 anode on the DSSC performance. We found that the addition of the dopant affects not only the electron lifetime, but also the dye adsorption as well. The best performance was obtained for zinc doped SnO2 anodes, with the power conversion efficiency of 3.4%.
