AI Technical Summary

Technical Problem

The traditional packaging film lacks friction during solar cell packaging, which makes it difficult to eliminate bubbles during lamination, affecting the lamination quality.

Method used

A packaging film consisting of interlaced warp lines and weft lines is designed, in which at least one of the warp lines and weft lines is wavy and forms a semi-permeable gap between two adjacent warp lines and two weft lines.

Benefits of technology

The friction of the adhesive film is increased through the staggered structure, which has excellent anti-slip performance. At the same time, the semi-permeable gap setting makes it easier to exhaust, significantly reduces the laminated bubbles of the component, and improves the shrinkage performance of the adhesive film and the efficiency of the production process.
