Abstract
Replacement of expensive platinum counter electrodes has been primarily focusing research on Dye-Sensitized Solar Cells. Here, we present a facile solution-processed thin-film nickel doped molybdenum oxide counter electrode as a cheap alternative of Platinum. The most motivation of doping nickel in molybdenum oxide was to explore the synergic effect produced due to hypo-hyper electronic d orbital coupling between the pair. These results show the shift of valence band energy level upwards to properly align with electrolyte redox potential for facilitating hole transport. We found that optimized 10 mol. % Ni doping yielded the maximum efficiency of the fabricated solar cells.
