Problems solved by technology
[0008] However, the disadvantage of the existing technology is that the nano-scale metal powder or oxide powder required by the ink printing method is not easy to manufacture, and the solvent required for making the slurry is not easy to prepare, so the ink printing method lacks a stable and reliable source. High degree of raw material

Embodiment Construction
[0015] The implementation of the present invention will be described in more detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it after studying this specification.
[0016] refer to image 3 , is a flow chart of the manufacturing method of the sol-gel solution of the CIGS solar cell of the present invention. Such as image 3 As shown, firstly, it starts from step S110. In step S110, a pre-mixing operation is performed, and the compounds containing copper, indium, gallium and selenium are mixed to form a metal compound mixture, and the diluent is added to the dispersant to form a diluted dispersant. Mixing agent, leveling agent and stabilizer to form a stable adhesive, mixing antifreeze and delayed coagulation agent to form an antifreeze coagulant, mixing reducing agent, metal complexing agent and refined metal solvent to form a metal reducing agent, and then entering step S120. In step S120, an advanced mixing operati...

Abstract
The invention discloses a method for preparing sol-gel solution of a copper-indium-gallium-selenium solar battery. The method comprises the following steps of: mixing a compound which comprises copper, indium, gallium and selenium, mixing a dispersing agent, an adhesive, a diluent, a leveling agent, an anti-freezing agent, a reducing agent, a stabilizer, a delayed coagulant, a metal complexing agent and a metal refining solvent, stirring with heating, stirring with cooling, and cooling to form the sol-gel solution. The sol-gel solution is provided for film processing such as printing, spraying, soaking or spin coating and the like so as to form a copper-indium-gallium-selenium light absorption layer of the copper-indium-gallium-selenium solar battery.
Description
technical field [0001] The invention relates to a method for manufacturing a solar cell, in particular to a method for manufacturing a sol-gel solution of a copper indium gallium selenide solar cell. Background technique [0002] With the gradual depletion of petrochemical energy, seeking stable and reliable alternative energy has become the biggest survival issue that all human beings have to face in this century, and various energy sources including biomass energy, geothermal energy, wind energy, and nuclear energy depend on the reliability of their sources. , use safety, and environmental protection considerations, are not comparable to solar energy from solar radiation, because sunlight can be received on the surface of the earth, and the light energy is only converted into electrical energy during use, without any Polluting substances are produced, so solar energy is currently the cleanest alternative energy source. [0003] A solar cell is a device that converts the l...
