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.

Perovskite solar modules (PSMs) have emerged as a promising photovoltaic technology due to their high efficiency and low manufacturing costs. However, the commercialization of PSMs faces significant challenges in achieving precise and reliable laser scribing processes for series interconnection. The laser scribing quality directly impacts the geometric fill factor (GFF), series resistance, and ultimate conversion efficiency of solar modules. This article systematically examines the monitoring techniques and quality control strategies for P1, P2, and P3 laser scribing processes that are essential for improving production yield in industrial manufacturing.
