NOVELTY - An electrode for a dye-sensitized solar cell, which is produced by preparing a substrate, sputtering the substrate with indium tin oxide in a sputter chamber to deposit an indium tin oxide film on a surface of the substrate, and subjecting the semi-finished product to a heat treatment carried out at a predetermined temperature.    USE - The electrode is used for manufacturing dye-sensitized solar cell (claimed).    ADVANTAGE - The electrode structure exhibits excellent and more uniform sheet resistance performance with low variation level. The electrode structure is especially suited for being used in a dye-sensitized solar cell to enhance its light-to-electrical conversion efficiency. The photosensitive particles coated on the working electrode are only a few microns in thickness. These nano-scale particles are so distributed as to form a stalactite-like fractal structure, which renders the effective light receiving surface area of the light sensitive layer one-hundred times greater than the surface area of the electrode. The solar cell may achieve high efficiency for light absorption by using rather slight amount of materials. The photosensitive particles can be easily and cost-effectively manufactured by immersing semiconductor particles in the dye-containing solution for 20 minutes and drying the particles with inert gas. There is no particular requirement for the surface roughness of the coated working electrode. Dye molecules normally have broad absorption spectra in the visible region that cover a wavelength range from ten up to a hundred nanometers and thus meet the requirement for capturing energy from a broad spectrum of sunlight by way of the same component. In quantum efficiency terms, dye-sensitized solar cells are extremely efficient in absorbing photons from the sunlight. A dye-sensitized solar cell is potentially to have minimal energy loss during the conversion of light to electricity.
