Preparation equipment and preparation method of half-piece battery

Abstract

The invention discloses preparation equipment and a preparation method of a half-piece battery. The preparation equipment of the half battery comprises a workbench, a feeding mechanism, photographing equipment, printing equipment and a discharging mechanism. The photographing equipment is arranged at the photographing table top to determine the position information of the half silicon wafer, and the printing equipment is arranged at the printing table top and is suitable for printing the corresponding half silicon wafer. Wherein a half silicon wafer enters the working table from the photographing table top and is moved out of the working table from the plate outlet table top, and the reserved table top provides a reserved position for the half silicon wafer. According to the preparation equipment of the half-piece battery, the half-piece silicon wafer is directly printed to prepare the half-piece battery, namely, the half-piece silicon wafer is not subjected to a segmentation process after printing, so that the phenomena of deformation, breakage and the like of the printed silicon wafer can be avoided, the yield of produced wafers can be improved, and the production cost is reduced. And the flaking design of the silicon wafer is easy to realize.

Description

technical field [0001] The invention relates to the technical field of photovoltaic cells, in particular to a preparation equipment and a preparation method of a half-cell battery. Background technique [0002] A solar cell is a device that uses the PN junction of semiconductor materials to separate electrons and holes, and export them through electrodes. Printing is the most commonly used metal electrode fabrication method. Conventional solar cells use quasi-square silicon wafers, and the final finished cells are also quasi-square. At the component end, the quasi-square battery is divided into half or multiple small batteries to reduce the power loss caused by the heating of the component. [0003] In addition, with the development of the solar energy industry, cost reduction is a problem that all solar energy companies must face, and large-scale and thin silicon wafers have become the trend of industry development in recent years. [0004] Cutting the cell in half or mu...

AI Technical Summary

Problems solved by technology

[0004] Cutting the battery in half or multiple small batteries will increase the cutting loss, especially not conducive to high-Voc high-efficiency batteries, and large-scale thin batteries have large deformation, easy fragments, and decreased coating uniformity, resulting in a decline in yield and efficiency
