Photonic Thin-Film Battery for Indoor Low-Light Energy Harvesting (3.8V)

The Photonic Thin-Film Battery is an ultra-thin, flexible energy harvesting solution designed to capture indoor ambient light. Delivering a 3.8V output from illumination levels as low as 50 Lux, it suits makers, engineering students, and IoT developers creating self-sustaining low-power electronics.

Ultra-thin flexible construction

Measuring only 0.2mm in thickness, this flexible thin-film battery seamlessly integrates into slim profiles and curved enclosures. The pliable form factor allows for unobtrusive placement in space-constrained maker projects.

Indoor low-light harvesting

Engineered for ambient indoor light conditions, the module converts surrounding room illumination into usable electrical energy. This makes it ideal for powering maintenance-free indoor sensors and standalone monitors.

50 lux operating threshold

The photonic cell operates in low-light environments starting from just 50 Lux. It reliably harvests energy even under dim artificial indoor lighting.

Integrated 3.8V output

The battery provides a 3.8V power output directly from harvested light. It delivers steady energy storage and voltage delivery for compatible low-voltage circuits.
