In the manufacturing of thin-film solar cells, such as perovskite cells, laser scribing (P1, P2, P3) and edge cleaning (P4) are critical processes that directly impact cell efficiency and production yield. Multi-beam synchronous processing technology stands as a pivotal innovation for enhancing manufacturing efficiency. LeCheng Intelligent, a leader in this field, achieves high-precision, high-throughput processing of large-area panels through advanced optical design, sophisticated motion control, and deep process integration.

The rapid expansion of the Internet of Things (IoT) has created an urgent need for sustainable power sources for wireless sensor networks and portable electronic devices. This article presents recent breakthroughs in flexible thin-film silicon photovoltaic modules fabricated on polyimide substrates, which demonstrate exceptional performance under indoor lighting conditions. Through optimized plasma-enhanced chemical vapor deposition (PECVD) processes and strategic material engineering, these lightweight, bendable solar modules achieve remarkable 9.1% aperture efficiency at 300 lux illumination while maintaining mechanical robustness through thousands of bending cycles. The technology offers a promising solution for powering the next generation of autonomous electronic devices without battery replacement constraints.
