36Kr has learned that Hunan Yanhe Technology Co., Ltd. (hereinafter referred to as "Yanhe Technology") recently announced the completion of nearly 100 million yuan in Series A1 financing. The investors in this financing are Guoke Investment and Huixin Investment. The funds will be mainly used to accelerate the construction progress of the production line at the Changde base in Hunan, promote the iterative upgrading of the core technology of perovskite batteries, and expand the global market layout.

"Yanhe Technology" is an enterprise that 36Kr has been following for a long time. It focuses on the production and R & D of consumer - grade perovskite photovoltaic battery components and related equipment. It has completed the delivery of nearly 100 million yuan in orders, and its products have entered the supply chain systems of more than 100 brands in more than 50 countries and regions around the world, including Lenovo, Aqara, Signify, Dreame and other leading domestic and foreign enterprises.

Yanhe Technology's production line

At the 2026 CES (Consumer Electronics Show in the United States), products such as photovoltaic electronic paper table cards, electronic photo frames, smart glasses, smart cameras, and smart doorbells jointly developed by "Yanhe Technology" and customers such as Xingtai Technology, Meikai Innovation, Jinyata, Weikuo Optoelectronics, Xunmei Zhilian, and anyfree Home were globally launched for the first time.

The core feature of the products of "Yanhe Technology" unveiled at CES is that by leveraging the characteristics of perovskite photovoltaic batteries, such as high photoelectric conversion efficiency, flexibility, light weight, and strong power generation performance in low - light conditions, they can be charged in low - light environments such as indoors, truly achieving "power generation wherever there is light". Moreover, they can be seamlessly integrated into the product structure, maintaining a simple appearance while reducing operation and maintenance costs and the environmental burden caused by battery waste.

Take the electronic photo frame jointly developed by "Yanhe Technology" and Jinyata as an example. Based on perovskite photovoltaic components and low - power electronic paper displays, this product uses a color E - ink display and integrates a photovoltaic module on the side. It does not require charging or battery replacement, enabling long - term maintenance - free operation.

Lux (lx) is a unit of illuminance, which measures the luminous flux of visible light received per unit area. Feng Fan, the CEO of "Yanhe Technology", introduced that the illuminance of direct sunlight on a sunny day is usually about 100,000 lux, and the low - light environment in an ordinary room is about 200 lux. Most products of "Yanhe Technology" (starting illumination < 20 lux) can be effectively charged in a low - light indoor environment of 200 lux without additional light - supplementing actions such as "sunbathing".

In terms of usage time, "Yanhe Technology" uses 4 - 5 hours of low - light power generation indoors as the energy - storage standard. The electricity collected during this period is stored in capacitors or lithium - ion batteries, which can meet the 7×24 - hour continuous use of low - power consumer electronic products such as smart wearables and portable IoT terminals, achieving a precise balance among power - generation efficiency, energy - storage capacity, and battery life requirements.

"Traditional products such as remote controls, smart doorbells, and electronic photo frames need to be connected to wires, plugged into sockets, or have their batteries replaced every six months or a year. Now, you don't have to worry about long - term battery replacement. As long as there is light, there is always power," Feng Fan summarized.

In addition to being "charge - free", to truly achieve a "seamless experience", the original combination of battery materials and products must also be realized. This requires that perovskite batteries can be customized in any shape, and even deformed such as punched or in a U - shaped arc. Feng Fan introduced that this is also the advantage of "Yanhe Technology"'s flexible production line.

Specifically, on the one hand, the perovskite battery cells provided by "Yanhe Technology" to customers can be made in larger sizes, allowing products to use the effective area to a greater extent . For example, the conventional size of the battery material for a smart door lock is 100 square centimeters. Considering factors such as the door - lock opening and the U - shaped size of the door lock, it can be made up to 200 square centimeters, achieving a breakthrough in the overall effective area.

On the other hand, in addition to the normal rectangular size, "Yanhe Technology" can deliver perovskite battery cells in sizes with round holes, U - shaped arcs, etc., which can be further integrated into the customer's product design system, achieving the original combination and enhancing the overall aesthetics of the product.

In addition to product performance, the environmental - protection attribute of "Yanhe Technology"'s perovskite photovoltaic batteries has also become a major focus of the products at CES. Feng Fan shared: "Many foreign friends care a lot about environmental - protection factors. A traditional remote control may require more than a dozen AA batteries over a five - to six - year usage cycle, and there is a risk of leakage if stored for a long time. With our help, it can truly achieve a maintenance - free state, generating power as long as there is light."

Cost is another important factor in bringing cutting - edge products to the market. The goal of "Yanhe Technology" is to make the overall cost of perovskite photovoltaic components + power management chips + energy - storage modules basically match that of six AA batteries. Currently, 80% of this goal has been achieved, and the final cost - structure goal is expected to be achieved this year.

During this participation in CES, "Yanhe Technology" also saw market opportunities in the fields of public facilities and equipment such as environmental - detection devices and smoke alarms from the feedback of the audience and customers. It signed trial - production orders with relevant customers to further expand the application scenarios of perovskite batteries.
