Recently, MANST’s independently developed core perovskite equipment successfully won a bid for a perovskite project from a leading customer in the industry, marking further recognition of the company’s technological capabilities and mass-production capabilities in the perovskite field.

The equipment awarded includes precision perovskite coating equipment, VCD vacuum drying equipment, and supporting automation robots. Among them, the core precision coating equipment supports substrates measuring 600 mm × 600 mm, providing critical equipment support for the customer’s large-scale mass production.

To meet the requirements of perovskite thin-film fabrication for large-area coating uniformity, process control precision, and drying stability, MANST’s perovskite coating and VCD vacuum drying equipment offer the following key advantages:

High Precision

MANST’s perovskite coating equipment is equipped with a self-developed high-precision injection pump and a corrosion-resistant coating die. It achieves coating thickness uniformity of ≤5%, providing critical equipment support for improving solar cell/module conversion efficiency.

The VCD vacuum drying equipment features rapid vacuumization and venting capabilities, achieving evacuation from atmospheric pressure to 10 Pa within ≤5 s. This rapidly establishes a low-pressure environment, providing the necessary conditions for subsequent solvent removal and thin-film drying. Meanwhile, precise control of the evacuation process helps reduce film Mura defects, such as color variations and streaks, caused by uneven pressure changes, balancing equipment operating efficiency with film quality.

Intelligent Control

MANST’s perovskite coating equipment integrates intelligent modules for substrate thickness measurement, foreign particle detection, pipeline pressure monitoring, coating die level and height correction, and liquid leakage detection. These modules monitor and correct key process stages, reducing the impact of abnormal conditions on the coating process. The Y-axis adopts an air-bearing design and supports fully automated closed-loop control, providing a stable motion control foundation for large-area precision coating.

The VCD vacuum drying equipment uses automatically controlled butterfly valves at the vacuum ports, supports adjustable evacuation rates and multi-stage drying recipe configuration, and enables programmable control of the evacuation process at different stages. This provides the process controllability and flexibility required for drying different products.

As one of the few companies globally with core technologies covering the entire perovskite production line, MANST has developed integrated technical solutions for single-junction and tandem coating, as well as vacuum coating, covering the full production process from R&D and pilot-scale testing to mass production. Focused on high-quality thin-film fabrication, these solutions provide equipment support for the large-scale manufacturing of perovskite products.

MANST also offers customers comprehensive turnkey services covering factory planning, equipment customization, process development, production line commissioning, and personnel training.

Among these solutions, China’s first flat-panel slot-die coating system designed for GW-scale production lines has, since its successful development, been deployed on production lines at several leading companies in China. The system features short production cycle times, minimal edge exclusion, and precise control of large-area coating thickness down to the nanometer scale. It has also achieved equipment deliveries for corresponding substrate sizes across different technology routes, including single-junction and tandem configurations, accumulating valuable industrialization experience in the localization of coating equipment.

This successful bid further demonstrates the customer's recognition of MANST’s technical solutions, equipment performance, and comprehensive service capabilities. It also lays a solid foundation for further cooperation and the smooth execution of the project. Going forward, MANST will continue to focus on customer needs, further integrate equipment technologies with actual production processes, and provide more comprehensive equipment support for the industrialization of perovskite technology, helping expand the application potential of perovskite photovoltaics.
