APS Launches Next-Gen High-Precision Slot Die Coating Systems, Empowering Mass Production Upgrade of Perovskite PV Cells

On October 22, 2025, Alpha Precision Systems (APS) — a veteran with over 30 years of experience in the microelectronics industry — officially unveiled its new generation of high-precision slot die coating systems. Boasting ±1μm coating accuracy, a 120m/min operating speed, and multi-scenario adaptability, the systems provide critical equipment support for thin-film-dependent industries such as photovoltaics (PV), displays, and microelectronics, and are expected to accelerate the commercialization of cutting-edge technologies like perovskite PV and Micro LED.

As a global leader in high-end coating equipment, APS developed the new product line based on its independently researched integrated process platform, with a core breakthrough in solving the uniformity challenge in large-area thin-film fabrication. According to APS’s Chief Technology Officer, traditional coating equipment often faces issues like over ±10nm film thickness fluctuation and increased grain boundary defects when scaling lab-scale processes to mass production — for example, the efficiency of perovskite modules may drop from 22.3% (10cm²) to 17.8% (1m²), leading to significant performance degradation. The new-generation system, however, controls the thickness deviation of large-area coating within ±1μm through optimized die design and real-time closed-loop control technology. It also integrates an intelligent crystallization regulation module to significantly reduce micro-defects such as pinholes and cracks, laying a solid foundation for the mass production of high-efficiency devices.

In terms of application expansion, the system achieves a "one-platform-for-multi-fields" breakthrough. For the PV industry, its customized coating solutions can adapt to the flexible substrates and high-viscosity slurries required for perovskite cells. Equipped with high-precision temperature and humidity control units, it effectively mitigates the poor photothermal stability and humidity sensitivity of perovskite materials, helping PV enterprises overcome mass production efficiency bottlenecks. In the display sector, the system has passed Micro LED thin-film encAPSulation verification, enabling nanoscale precision coating for ultra-fine pixel structures — a key step in promoting the popularization of high-definition, low-power Micro LED displays. Additionally, it supports the R&D and production of thin-film devices in biomedical and fuel cell fields, such as high-sensitivity biosensors and proton exchange membranes, further expanding APS’s service scope across emerging high-tech industries.

"For over three decades, APS has focused on solving 'unscalable' pain points in thin-film technology," said an APS spokesperson. "The launch of the new-generation system is not just an upgrade of equipment performance, but a strategic empowerment for global customers to accelerate technological iteration and cost optimization." Currently, the system has received pre-orders from leading enterprises in PV, display, and biomedical sectors, with the first batch of deliveries scheduled for Q1 2026.
