Manufacturing Method of Naural Dye Solution for Dye-Sensitized Solar Cell and Natural Dye-Sensitized Solar Cell using the same

摘要

PURPOSE: A manufacturing method of a natural dye solution is provided to provide a natural dye solution capable of manufacturing various natural dye-sensitive solar batteries for requiring growth of plants. CONSTITUTION: A manufacturing method of a natural dye solution comprises a step of preparing a natural dye powder (400); a step of forming a natural dye solution by mixing the natural dye powder, pH controller, and solvent; and a step of forming a natural dye solution by mixing the natural dye powder, pH controller, and solvent. The natural dye solution has a wavelength selectivity for promoting or inhibiting growth of plant. The natural dye is Carthami Flos xanthophyll, lac color, alive side, red cabbage pigment, gardenia red, gardenia blue, rdenia Yellow, cacao, cochineal, henna, or monascus red. The manufacturing method is provided to control wavelength range by using the pH controller.
