Special solar energy high power spotlighting steel mesh with positioning irregular holes

Abstract

The invention relates to a special solar energy high power spotlight steel mesh with positioning irregular holes and belongs to the technical field of solar photovoltaic electricity generating. The special solar energy high power spotlight steel mesh with the positioning irregular holes for the solar energy comprises a frame, a stainless steel piece, an irregular array hole and a positioning hole; the stainless steel piece is fixed on the frame; the irregular array hole and the positioning hole in the same size are engraved on the stainless steel piece. According to the special solar energy high power spotlight steel mesh with the positioning irregular holes, a spotlighting photovoltaic battery piece is tightly adhered to an area after solder paste on the irregular array hole is heated and melted; the positioning hole can accurately position the spotlighting photovoltaic battery piece to improve the product yield; production and manufacturing can be performed rapidly and the production efficiency is improved.

Description

technical field [0001] The invention relates to a special steel mesh for high power concentrating solar energy with positioning irregular holes, and belongs to the technical field of solar photovoltaic power generation. Background technique [0002] In today's world, global power generation mainly relies on water power and fire power, but their pollution is quite serious. With global warming, countries around the world are developing clean energy. Although nuclear energy brings us better choices, it For example, the Japanese tsunami, the nuclear power plant was directly destroyed, and the nuclear radiation has brought considerable harm to the local area, so that solar power is now also being sought. Solar power generation has become a new way for the world to obtain energy. Ordinary solar power generation has a low conversion rate. The current new technology represented by high-power concentrating solar power is the focus of world attention. [0003] Compared with low-power...

Problems solved by technology

[0003] Compared with low-power concentrating solar systems, high-power concentrating solar energy can achieve higher conversion efficiency and higher commercial cost performance. High-power concentrating solar receiver modules are the core of high-power concentrating solar power generation systems, and they are also The most valuable part of the system, the quality and cost of the high-power concentrated solar receiver module will directly affect the quality and cost of the entire system, but during production, the cells cannot be accurately fixed on the battery substrate, resulting in high-power concentrated solar energy The production yield of the receiver module is reduced. Even if it is bonded to the battery substrate, after the product module is assembled, the sunlight cannot be accurately concentrated on the effective area of ​​the receiving surface of the battery sheet, which will cause a decrease in conversion efficiency, and in severe cases, it will cause reception failure. How to fix the high-power concentrating solar cells on the battery substrate accurately and improve the yield rate of the product will be an urgent problem to be solved.
