Abstract

The invention discloses a solar battery texturing device. The device comprises a detection box shell and a dust blowing device, a dust cover is arranged on the top of a box body of the detection box, and the outer side of the dust blowing device is provided with a main machine shell; an air outlet is formed in the upper surface of the main machine shell. According to the device, after hot drying is carried out, the temperature and humidity of a solar battery are conveniently detected, final dust removal is also facilitated, the device has a certain dust removal function, the qualified rate can be increased conveniently, a certain non-qualification alarm function can be achieved, and the device is convenient and fast to use, diversified in function and long in service life. Dust on the surface of a solar panel is blown away conveniently through a dust blowing air pump and a dust blowing brush head; the dust on the surface of the solar panel is conveniently wiped away by means of a sponge mat on the brush head, the dust on the panel is removed, and then the cleanliness of the surface of the solar panel is effectively ensured in the texturing process, and the solar panel production efficiency is conveniently guaranteed.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a solar cell texturing device. Background technique [0002] One of the solar cell manufacturing processes refers to obtaining a pyramid-like or worm-like suede structure on the surface of a single crystal silicon wafer through certain processing methods to increase the number of reflection and refraction of light on the surface of the cell, thereby reducing the surface reflectance. Cell texture methods include: mechanical groove, laser groove, chemical corrosion. Among them, chemical corrosion is the most commonly used because of its low cost, good texturing effect, and controllable reaction process. The texturing of monocrystalline silicon is generally based on the principle of the difference in the isotropic corrosion rate of monocrystalline silicon with an alkaline solution such as sodium hydroxide, and the chemical reaction process is carried out to obtain a pyramid-sha...
