AI Technical Summary

Technical Problem

In existing photovoltaic cell modules, shingled technology reduces the light-receiving area of ​​the cells, results in insufficient mechanical strength, increases the cost of connectors and reduces production efficiency, and easily causes microcracks in the cells.

Method used

The photovoltaic cells are connected by overlapping. By setting first and second overlapping sections at the edge of the cells and forming notch structures on both sides, adjacent cells overlap at the edge, ensuring the photoelectric conversion efficiency and mechanical strength of the photovoltaic cells, while avoiding stress concentration.

Benefits of technology

It improves the photoelectric conversion efficiency and mechanical strength of photovoltaic cells, reduces production costs and the risk of microcracks, and enhances the structural stability and reliability of modules.
