AI Summary

Researchers from Hebei Normal University of Science and Technology in China have created an electromagnetic‑thermal strategy to enhance heating uniformity in photovoltaic module laminators. The method uses stepped aluminum magnetic shielding, zone‑specific currents, and temperature‑based current control to spread heat evenly across the heating plate. Uneven heating can leave encapsulants under‑cured in cooler spots or damage them and the cells in hotter areas. The team built a finite‑element model to reduce computational cost and validated its accuracy with a physical prototype.
