Abstract

The invention relates to a solar-grade crystalline silicon slicing process. The invention mainly solves the problems of low efficiency, high cost and poor benefit of existing solar-grade crystalline silicon slices. The process includes 1) fixation; 2) cutting; 3) glue removal; 4) film loading; 5) cleaning: 6) drying; 7) inspection; 8) storage. The solar-grade crystalline silicon slicing process, through a reasonable process, has reduced the undesirable phenomena such as fragments, lobes, thick slices, line marks, and missing corners during the slicing process of crystalline silicon. Due to the improved combination of mortar formula The speed, feed and other factors make the tangent thread reusable, which greatly reduces the production cost, improves the operation efficiency, and greatly improves the benefit.

Description

technical field [0001] The invention relates to the technical field of slicing processing of polycrystalline silicon, in particular to a solar-grade crystalline silicon slicing process. Background technique [0002] Solar energy is a kind of new energy. The practical use of solar energy has made great progress for human beings. It can play a role in environmental protection and energy saving, make full use of natural resources, and bring infinite convenience to human life. The realization of solar energy is to convert solar energy into electrical energy through solar panels, and then provide it for human use. The solar panel is naturally produced by chemical and physical reactions on silicon wafers, and the cutting of silicon wafers is one of the important steps in the completion of solar panels. . The existing slicing process has undesirable phenomena such as easy fragments, lobes, thick and thin slices, line marks, and missing corners during the silicon wafer cutting proc...
