Yanhe Technology

Yanhe Technology, established in February 2024, is a company focused on the research, development, and manufacturing of perovskite solar cell modules. The company's CEO is Feng Fan, and its team includes researchers from Peking University and Columbia University. Yanhe has secured substantial funding from a number of prominent institutions. An angel round included investors like Sparkedge Capital, Hunan Caixin Group, and China Glory Capital. This was followed by a Series A round of over RMB 100 million (USD 14 million) led by Orient Jiafu Asset Management, with participation from Empyrean Venture, Xingxiang Investment Holding Group, CASVC, and Morning Spring Venture. A subsequent Series A1 round raised nearly RMB 100 million from investors Guoke Investment and Huixin Investment.

The company's business model revolves around providing advanced energy solutions for the AI and Internet of Things (AIoT) sectors. It targets a wide array of markets, including consumer electronics, smart wearables, smart homes, portable energy storage, automotive photovoltaics, and even space applications. Yanhe has already formed partnerships with brands in Asia, North America, and Europe, and has entered the supply chains of over 100 brands, including Lenovo, Aqara, and Signify.

Yanhe Technology's core products are its perovskite solar cells and flexible solar modules, which are designed for high stability, photoelectric conversion efficiency, and cost-effectiveness. The company offers two main product lines: the Qiguang Series and the Qiongyin Series. The Qiguang modules are engineered for ultra-low-power electronics, are 0.5 mm thick, and can operate effectively even in low indoor light. The Qiongyin Series provides similar performance but with enhanced flexibility, featuring a minimum thickness of 0.2 mm and the ability to bend around a 2 cm radius, making them suitable for curved devices like smart bands. These products aim to replace traditional batteries by harnessing ambient light, thereby extending the operational life of devices and reducing maintenance costs. A key milestone for the company was receiving one of the first IEC 63163:2021 certifications for perovskite solar cells from TÜV Rheinland, which validates the technology's reliability and stability.

To support its operations, Yanhe has established a significant manufacturing and R&D footprint. This includes a 100-megawatt fully automated perovskite production line in Changde, Hunan, which began full operations in August 2025. Additionally, the company runs a 10-megawatt pilot production and R&D facility in Beijing and has a sales center in Shenzhen. Yanhe plans to expand globally by establishing subsidiaries in Europe and North America and has a 500 MW automated flexible production line scheduled to come online.
