AI Technical Summary

⚠Technical Problem

Existing fully open steel plates are prone to insufficient paste coverage at the printing direction exit due to lateral shearing force, resulting in low or incomplete grid line height, or even breakage, which affects the cell conversion efficiency.

⚗Method used

A fully open steel plate is designed to solve the problem of local grid breakage. By setting a first transition hole with a shorter width and a first transition bridge with a first transition notch, the connecting bridge structure is optimized, the influence of lateral shear force on slurry distribution is reduced, and the slurry is ensured to cover the surface evenly.

🎯Benefits of technology

This resulted in more uniform slurry coverage, smoother and more unbroken grid lines during printing, and improved cell conversion efficiency.
