Embodiment 1

[0066] Use copper foil as the base material, use organic solvent to remove the oil stain on the surface, then impregnate the copper foil with dilute hydrochloric acid to remove the oxide skin on the surface of the copper layer of the base material, rinse with deionized water to remove the copper ions and chlorine on the surface of the copper layer of the base material ions, then dry the surface with high-purity inert gas at 50-70°C, use 0.5mol / L dilute hydrochloric acid solution as the liquid, put the cleaned copper foil into it, and connect it to the negative electrode; place gallium on the copper foil Located near the negative end of the power supply; insert the platinum electrode, connect to the positive pole of the power supply, and do not contact with copper foil and gallium; control the temperature of the above dilute hydrochloric acid solution to 50°C, adjust the power supply voltage to 12V, power on for 30 minutes, power off, and take out the copper foil and wash. Afte...

Abstract

Provided is a preparation technology for metal thin film. The method comprises the steps that a parent material and a base material are placed in a same conducting solution, and the contact between the parent material and the base material is kept; the parent material is driven to diffuse on the base material through the movement of electrons in the conducting solution to form the metal thin film.The chemical composition of the metal thin film is CuGaa, wherein a is greater than 0 and less than or equal to 7, or CuGabInc, b is greater than 0 and less than or equal to 7, and c is greater than0 and less than or equal to 7, or CuGadIneSef, wherein d is greater than 0 and less than or equal to 7, e is greater than 0 and less than or equal to 7, and f is greater than 0 and less than or equalto 7. The preparation technology for the metal thin film has the following advantages that (1) the vacuum environment is not needed, and the equipment investment is not high; (2) the film layer crystallinity degree is high, compositions are stable, and the bonding strength is high; (3) toxic compounds are not needed to be used, and the metal thin film is green and environmentally-friendly; (4) themetal thin film can be prepared under a self-diving mode without an additional power supply; and (5) a large area of film preparation can be achieved.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic cell equipment, and in particular relates to a metal film preparation process. Background technique [0002] Energy is an important material basis for economic and social development. At present, more than 90% of the world's industrial energy is provided by fossil energy such as coal, oil and natural gas. No matter from the perspective of the world or China, conventional energy is very limited. Therefore, with the gradual reduction of fossil energy and the increasingly serious environmental pollution, the development of new, environmentally friendly renewable energy and energy conversion technology has attracted great attention from all countries in the world. Among them, the solar cell power generation technology using photoelectric conversion is the best choice to solve the above two problems of energy and environment at the same time, so the research and development of solar cells are att...
