Abstract

The invention provides a production system of a polycrystalline solar cell, and aims at solving the technical problems that an existing production system is too simple in structure, texturing, diffusion, coating and sintering cannot be continuously carried out, the production speed is low and the like. The production system of the polycrystalline solar cell comprises a mounting frame, wherein the mounting frame is sequentially provided with a texturing device, a diffusion device, a coating device and a sintering device. The production system has the advantage of high production efficiency.

Description

technical field [0001] The invention relates to a production system of polycrystalline solar cells. Background technique [0002] A solar cell is a photoelectric element that converts light energy into electrical energy. Its basic structure is composed of P-type and N-type semiconductors. Under the irradiation of sunlight, the electrons in the P-type semiconductor are excited to leave holes, forming a potential difference with the N-type semiconductor. If the electrodes are connected with wires outside the P-type and N-type semiconductors, a loop will be formed. generate current. Solar cells are doped with different impurities in semiconductors to make P-type and N-type semiconductors. Generally, high-purity silicon wafers are used as substrates. Through cleaning, texturing, phosphorus diffusion, deposition, printing, sintering, packaging, etc. Process made. [0003] After searching, for example, Chinese patent literature discloses a solar silicon cell production system [...
