Abstract

The invention discloses a crystalline silicon solar cell manufacturing process. The process comprises the steps that step 1, a silicon wafer is cleaned, and then a flock surface is made; step 2, cleaning is performed before diffusion, and then phosphorus diffusion is performed; step 3, peripheral etching is performed, and then back junctions are removed; step 4, back electrode printing is performed, and then positive and negative electrode printing is performed; step 5, an antireflection film is prepared, then sintering is performed, and finally testing and grading are performed. The crystalline silicon solar cell manufacturing process has the advantages of being simple and lower in production cost and enabling the cell panel quality to be better.

Description

technical field [0001] The invention relates to the field of petroleum machinery, in particular to a manufacturing process of a crystalline silicon solar cell. Background technique [0002] A solar panel is a device that directly or indirectly converts solar radiation into electrical energy through the photoelectric effect or photochemical effect by absorbing sunlight. The main material of most solar panels is "silicon", but the production cost is so high that It also cannot be widely and universally used in large numbers. Compared with ordinary batteries and rechargeable batteries, solar batteries are green products that are more energy-saving and environmentally friendly. [0003] In the prior art, the existing solar panel production process is complicated, resulting in high production cost. [0004] To sum up, in the process of realizing the technical solution of the invention in the embodiment of the present application, the inventor of the present application found th...
