Abstract
A dye-sensitized solar cell has a working electrode, electrolyte, and counter electrode. The counter electrode includes a nickel (Ni) foam, titanium (Ti) foam, manganese (Mn) foam, or molybdenum (Mo) foam, and has a surface that is nitrided. The reaction efficiency for the solar cell is enhanced by the increased surface area reacting with the electrolyte, which results from using a metal foam. Mechanical properties, such as strength and ductility, and electroconductivity are improved due to the use of metals. The production costs are reduced by using substitute materials, which are low-cost and have oxidation-reduction efficiency.
