The core-shell SnO2@AO (A =Ni, Cu, Zn and Mg) films were prepared and the effects of coatings on photovoltaic properties were investigated Studies on X-ray photoelectron spectroscopy, energy dispersive X-ray analysis and transmission electron microscopy showed the formation of divalent oxides on the surface of SnO2 nanoparticles It was commonly observed that all the dye-sensitized core-shell films exhibited higher photovoltage than the bare SnO2 film Trans tent photovoltage measurements confirmed that the Improved photovoltages were related to the decreased time constants for electron recombination
