Barium Staminate as Semiconductor Working Electrodes for Dye-Sensitized Solar Cells

Barium Staminate as Semiconductor Working Electrodes for Dye-Sensitized Solar Cells

Dye-sensitized solar cells (DSSCs) are fabricated with perovskite-type BaSnO3 as the photoelectrode materials. Different preparation methods including coprecipitation, hydrothermal, and solid state reaction are employed to synthesize BaSnO3 particles to optimize the photoelectric activities of elect...
