Abstract
A method for preparing a sol-gel solution is provided. During a first stage mixture preparation process, a metal compound mixture is obtained by mixing compounds of Cu, In, Ga, and Se, a diluting dispersant is obtained by adding a diluent into a dispersant, a stabilizing adhesive is obtained by mixing a stabilizer, a leveling agent, and an adhesive together, an anti-freezing coagulant is obtained by mixing an anti-freezer with a retarding coagulant, and a metallic reducing agent is obtained by mixing a reducing agent, a metal complexing agent with a metal abstracting solvent. Then, the metal compound mixture, the diluting dispersant, the stabilizing adhesive, the anti-freezing coagulant, and the metallic reducing agent are mixed, heated and stirred, and then cooled down to obtain a sol-gel solution. The sol-gel solution can be provided for the ink coating technology for configuring the CIGS light absorbing layer of the CIGS solar cell.
