Solar cell coating graphite boat sheet and graphite boat

Abstract

The invention discloses a solar cell coating graphite boat sheet and a graphite boat, and relates to the technical field of solar cell coating. Aiming at the problems that the surface of a silicon wafer is easily scratched in the insertion process of the film-coated silicon wafer of a solar cell to form scratches so as to influence product quality, and the silicon wafer is easy to generate displacement in the insertion process when the silicon wafer is fixed by the electromagnetic force, the following technical scheme is provided: the solar cell coating graphite boat sheet comprises a graphiteboat and graphite boat sheets, and the graphite boat is formed by connecting a plurality of graphite boat sheets side by side. According to the invention, the position between every two graphite boatsheets can be adjusted, so that the surface of the silicon wafer can be prevented from being abraded and scratched by the graphite boat sheets when the silicon wafer is inserted, and the silicon wafer can be limited by corresponding thicknesses through the graphite boat sheets, wherein the graphite boat sheets can be conveniently pushed outwards through the rotary horizontal movement of the pushcylinder through the threaded screwing connection design of the push cylinder on the outer surface of the connecting shaft, so that the distance between the two graphite boat sheets is increased.

Description

technical field [0001] The invention relates to the technical field of solar cell coating, in particular to a solar cell coating graphite boat sheet and a graphite boat. Background technique [0002] Solar cells, also known as "solar chips" or "photovoltaic cells", are photoelectric semiconductor sheets that use sunlight to generate electricity directly. As long as it is illuminated by light that meets certain illumination conditions, it can output voltage instantly and generate current when there is a loop. In physics, it is called solar photovoltaic, or photovoltaic for short. A solar cell is a device that directly converts light energy into electrical energy through the photoelectric effect or photochemical effect. There are three basic characteristics of volt-ampere characteristics of electric environmental protection batteries. Solar cells are mainly based on semiconductor materials. Their working principle is to use photoelectric materials to absorb light energy and t...

Problems solved by technology

[0004] A kind of solar cell coated graphite boat sheet and graphite boat proposed by the present invention solve the problem that when the coated silicon chip of the existing solar cell is inserted into the graphite boat, because the distance between the graphite boat sheets is small, the , the surface of the silicon wafer is easily scratched, forming scratches, which affects product quality. When the silicon wafer is fixed by electromagnetic force, the silicon wafer is also prone to displacement during the insertion process.
