Abstract

The invention relates to a method for using alkaline liquor to clean a substrate used for preparing a dye-sensitized solar cell. The method comprises the following steps: immersing the substrate into the alkaline liquor, and causing the alkaline liquor to submerge the top of the substrate for 8+-3mm; ultrasonically cleaning for 0-60 minutes at 0-50 DEG C, washing the substrate with deionized water, and drying the substrate. The method uses the inorganic alkaline liquor to replace an organic solvent to clean the substrate, and the dosage of the alkaline liquor is less, so that the cleaning cost can be reduced, and the harm for operators and environment is reduced. Waste liquor after cleaning can not be recycled to be directly drained into a drainage channel, and the problems of large amount of waste liquor and difficult recycle are solved.
