It was reported that at SCE 2025, a leading Chinese consumer electronics event, Yanhe Technology showcased its Qiguang and Qiongyin perovskite photovoltaic series, reportedly attracting strong interest and signing multiple strategic agreements on-site.
Designed for a wide range of applications - including smart homes, wearables, and portable electronics - Yanhe’s solutions prioritize lightweight, compact designs that significantly extend device battery life. “Consumer electronics are increasingly demanding in terms of power and flexibility. Perovskite technology offers a compelling alternative to conventional photovoltaics,” said a Yanhe representative during a live product demonstration. “From wearables to edge computing, we see energy efficiency as the next critical frontier.”
He added: “A 10 cm² perovskite cell can match the lifetime output of 20 AAA batteries or 50 button cells. By harnessing ambient light, we’re eliminating the burden of battery replacement while enabling more sustainable, cost-effective solutions.”
The Qiguang Series is engineered for ultra-low-power electronics. Delivering up to 20 mW/cm² under direct light and maintaining 9–180 μW/cm² indoors (100–1000 Lux), it performs reliably across lighting environments. At only 0.5 mm thick and less than 0.15 g/cm² in weight, Qiguang modules are both efficient and highly customizable.
The Qiongyin Series mirrors Qiguang’s performance while offering enhanced flexibility. With a minimum thickness of 0.2 mm and the ability to bend around a 2 cm radius, Qiongyin modules are ideal for curved wearables like smart bands and rings.
Both series are available in Plus editions, integrating control circuits and energy storage for plug-and-play deployment. These modules enable AI-powered smart devices to operate in a “photosynthesis mode” using indoor light—paving the way for truly autonomous, light-powered devices.
Yanhe’s operational footprint includes a 100 MW automated production line in Changde (Hunan), a 10 MW R&D pilot line in Beijing, and a sales and marketing hub in Shenzhen - establishing a full-stack platform from innovation to industrial-scale delivery.
In a major milestone, Yanhe recently secured one of the world’s first IEC 63163:2021 certifications for perovskite solar cells from TÜV Rheinland, validating the high reliability and long-term stability of its technology. Additional certifications, including RoHS and REACH, position Yanhe as a ready partner for sustainable electronics manufacturing worldwide.
