Solar cell preparation combination method and preparation device

Abstract

The invention discloses a solar cell preparation combination method and preparation device, and belongs to the technical field of solar cell preparation. The device comprises an impurity removal chamber, a through hole is formed in the side surface of the impurity removal chamber, an electric transmission belt is inserted into the through hole, and an electrostatic electret chamber is arranged atthe periphery of the electric transmission belt; and an anode piano wire mounting seat is arranged on the inner side wall of the electrostatic electret chamber. According to the invention, through themutual cooperation of the designed electrolyte solution, the electrostatic electret chamber, the positive piano wire, the electrolytic reaction generation chamber, the molybdenum net cage and the molybdenum net partition plate, fallen fluff in the suede can be effectively removed, and the dust in the suede is driven by the fluff to move towards the direction of the probe, so the dust removal andfluff removal efficiency is high; the electrolytic reaction generation chamber can be prevented from having more impurities in the electrolytic reaction process, a phosphorosilicate glass layer formedon the surface of the silicon wafer plate can be effectively removed, the effect is higher compared with acid pickling, and a diffusion dead layer on the surface of the silicon wafer plate can be effectively removed.

Description

technical field [0001] The invention belongs to the technical field of solar cell preparation, and in particular relates to a solar cell preparation combination method and a preparation device. Background technique [0002] A solar cell 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 due to the high production cost, it There are still certain limitations in its widespread use. Compared with ordinary batteries and rechargeable batteries, solar batteries are green products that are more energy-saving and environmentally friendly. [0003] In the manufacturing process of solar cells, the production process of solar cells is divided into silicon wafer detection - surface texturing - diffusion junction - dephosphorous silicon glass - plasma etching - anti-reflection coating - screen printing - rapid sinter...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the traditional pickling method is still adopted for the dephosphorous silicon glass used in the preparation of solar cells, the efficiency is low, and it is difficult to remove the diffusion dead layer formed on the surface of the solar cell, the concentration of the acid solution is high, It is easy to damage the silicon wafer board, and the acid solution concentration is low, which is not conducive to the removal of the diffusion dead layer, which seriously affects the photosynthetic efficiency of the finished solar cell, and a large amount of unfixed fluff and dust are likely to exist in the suede surface of the silicon wafer board, resulting in the presence of The problem of more impurities, and proposed a solar cell preparation method and preparation device
