The manufacturing method solves the technical problems that the existing solar cell panel has norelated manufacturing method, the batch manufacturing cannot be realized, and the manufacturing is tedious. The manufacturing method of solar cell with four layers of anti-reflection films comprises the following steps: a silicon wafer detection; b, surface texturing; c, diffusion junction; d, dephosphorized silica glass; d, etching; f, film plating; g, silk-screen printing; and h, sintering. Themanufacturing method provided by the invention has the advantage of being simple in manufacturing.

Description

technical field [0001] The invention belongs to the technical field of solar cells, and relates to a manufacturing method, in particular to a manufacturing method of a solar cell with four layers of anti-reflection films. Background technique [0002] With the rapid development of science and technology, economy and population, people have developed more and more new energy sources, including wind energy, solar energy, nuclear energy, etc. Compared with traditional chemical energy, they have the advantages of being renewable and clean, among which solar energy A solar cell is used as a conversion device, which converts light energy into electrical energy. In the solar cell structure, the anti-reflection film has an important influence on the efficient and reasonable use of the solar spectrum by the cell, and can directly affect the photoelectric conversion efficiency of the cell. [0003] After searching, for example, Chinese patent literature discloses a double-layer anti-...
