NGK INSULATORS and Ambient Photonics are collaborating to develop sustainable power products for maintenance-free connected devices that reduce reliance on disposable batteries.
The sustainable energy products combine solar cells from Ambient, which generate 3x more power than conventional indoor amorphous silicon solar cells, and “EnerCera pouch” lithium-ion rechargeable batteries from NGK, which offer the benefit of a low self-discharge current and stable charge/discharge cycles. The combination delivers efficient charging in low-light scenarios and power storage for extended periods of time.
This combined power features are in high demand as connected device manufacturers explore new designs to reduce their carbon footprint while expanding device capabilities. The Ambient and NGK technologies are also very thin, offering industrial designers a wide degree of flexibility.
Ambient has solved both the low power density and high cost problems of legacy low light PV technologies and created the most powerful low light energy harvesting solar cells. A single-sided LLI (low-light indoor) solar cell, and a new, first-of-its-kind LLI Bifacial solar cell that harvests energy from the front and back side of the solar cell simultaneously are available.
“When it comes to energy harvesting applications in IoT and other connected devices, battery performance and industrial design are critical considerations,” says Bates Marshall, CEO and Co-founder of Ambient Photonics. “As the industry evaluates new technologies to lower emissions, it’s technologies such as NGK’s EnerCera pouch that deliver both a power and aesthetic advantage that will ultimately make the transition away from disposable batteries a reality.”
“Ambient Photonics and NGK share a sustainability forward vision” says NGK’s Vice President of Global Business Creation and Corporate NV Creation, Iwao Ohwada. “The combination of their superior solar cell performance with our battery performance will expand the variety of potential disposable-battery-free applications and markets.”
