Industry First: Maxwell Wins Breakthrough Full-Line Order for Perovskite/SHJ Tandem Cell Solution
Time: 2025.12.26

Recently, Maxwell officially signed a full-line supply contract for Perovskite/SHJ tandem cells with a Chinese new energy enterprise, successfully securing the Company’s first commercial full-line order in the tandem cell field. This collaboration will enable the customer to build a leading-edge mass production line for G12H full-size Perovskite/SHJ tandem cells.​

Maxwell’s full-line tandem cell solution leverages the G12H large-size & full-area technology platform, covering the entire cell manufacturing processes, and delivers comprehensive advantages including high efficiency, large capacity, intelligence, automation, and cost-effectiveness. The Solution integrates several core technologies, such as: vacuum technology delivering high film quality and stability, pre-deposition printing technology that significantly reduces material costs, inkjet printing technology combining high material utilization with high throughput, and efficient, high-throughput plate-type temporal Atomic Layer Deposition (ALD) technology.​

Empowered by this integrated solution, the customer will be able to accelerate the development of its Perovskite/SHJ tandem cell R&D system and industrialization capabilities, strengthen systematic control over key processes, and advance the forward-looking deployment of patents and technology strategies, thereby establishing long-term core competitive advantages.​

The successful landing of this full-line order not only validates Maxwell’s leading expertise in tandem cell equipment and integrated solutions, but also marks a pivotal leap for large-size, high-efficiency Perovskite/SHJ tandem cell technology from lab to fab. This milestone is set to accelerate the industry’s transition toward hundred-megawatt-scale mass production.

Looking forward, Maxwell remains committed to deepening its R&D and innovation in high-efficiency cell technologies and core equipment, continually paving the way for the technological advancement, cost reduction, and efficiency gains in the photovoltaic industry.
