From energy harvesting, power management to storage — building a complete micro-energy supply chain
Light-tracking OPV technology achieves efficient photoelectric conversion under 200-500 lux indoor light, compatible with LED, fluorescent, and other light sources
Dedicated harvesting IC with quiescent current as low as 200nA, cold-start at VSI≥2V (ISI>10µA), up to 90%+ conversion efficiency, enabling efficient microwatt-level energy collection and management
High-performance lithium supercapacitors, second-level fast charging, 50F cycle life over 1 million, supporting micro-energy intermittent charging and instant high-power discharge
From light harvesting to load power, providing one-stop integrated solutions of IC + device + algorithm to accelerate product deployment
Covering the full micro-energy supply chain: harvesting, management, storage
Ultra-low power energy harvesting and management IC, supporting PV/thermoelectric/piezoelectric sources, cold-start at VSI≥2V (ISI>10µA), designed for indoor low-light environments.
