Solar energy base plate for improving fracture strength

Abstract

The invention discloses a solar energy base plate for improving the fracture strength, which includes a first upper surface, a plurality of first convex structures and a plurality of first concave zones, wherein the first convex structures are formed on the upper surface; and the first concave zones are formed on the peripheries of the first convex structures. According to the invention, the combination of the first convex structures and the first concave zones improves the fracture strength of the solar energy base plate, thereby resisting high tension deflexion.

Description

technical field [0001] The present invention relates to a solar substrate, and more particularly to a solar substrate for improving fracture strength. Background technique [0002] Generally speaking, conventional solar cells mostly use semiconductor wafers such as silicon as substrates. However, since silicon and other semiconductor wafers are hard and brittle materials, they are easily impacted by external forces, especially those caused by the solar cell assembly process, resulting in cracking of silicon and other semiconductor wafers. In addition to solar cells, silicon wafers are widely used in the manufacture of many semiconductor components. In addition, due to the shortage of silicon raw materials due to the increase in demand for semiconductor components, how to avoid undue waste of silicon raw materials (such as cracking due to external impact) and improve the yield of the process is an urgent problem to be solved. Taking a solar cell as an example, if the solar ...
