Example Embodiment
[0058] Now referring to the drawings, specific embodiments of the present invention will be described in detail. What is described here is only the preferred embodiments of the present invention, and those skilled in the art may think of other ways to implement the present invention on the basis of the preferred embodiments, and the other ways also fall within the scope of the present invention.
[0059] The production of crystalline silicon cells requires multiple steps. For monocrystalline silicon cells, it can be obtained as follows. For example, using the Czochralski method to grow wafer rods as raw materials. Use a square-cutting machine to square and slice, square and polish the wafer rod to obtain a square rod, and then slice the square rod obtained after square-cutting and grinding to obtain a single crystal silicon wafer. Then, the monocrystalline silicon wafer is subjected to steps such as surface texturing, cleaning, diffusion bonding, removal of phosphorous silicate...
