High concentrated photovoltaic cell bonding and printing steel mesh with positioning function

Abstract

The invention relates to a high concentrated photovoltaic cell bonding and printing steel mesh with a positioning function, and belongs to the technical field of solar photovoltaic power generation. The high concentrated photovoltaic cell bonding and printing steel mesh with the positioning function comprises a frame, a printing hole array, a stainless steel sheet and a positioning hole, wherein the stainless steel sheet is fixed on the frame, and the printing hole array is formed in the stainless steel sheet in an engraving mode. After solder paste on the printing hole array is heated and melted, a concentrating photovoltaic cell sheet tightly adheres to a region through the solder paste and will not move or deviate; the concentrating photovoltaic cell can be more accurately positioned by the positioning hole, and therefore the percent of pass of products is improved; production and processing can be faster conducted, and therefore production efficiency is improved.

Description

Problems solved by technology

[0003] Compared with low-power concentrating systems, high-power concentrating photovoltaics can achieve higher efficiency and higher cost performance. The high-power concentrating receiver module is the core of the power generation system, and it is also the most valuable part of the power generation system. The quality and cost of the receiver module will directly affect the quality and cost of the entire system. However, during production, the cells cannot be accurately fixed on the cell substrate, resulting in a decline in the production yield of the high-power concentrating receiver module. On the substrate, after the product module is assembled, the solar light cannot be accurately concentrated on the effective area of ​​the receiving surface of the cell, which will cause a decrease in the conversion rate, and in severe cases, will cause some original parts of the receiver module to be burned. It will be an urgent problem to be solved to fix the chip on the battery substrate accurately and improve the yield rate of the product.
