Problem
Many low-power IoT and smart home devices rely on disposable batteries, contributing to environmental waste and requiring frequent replacements. Existing indoor solar cells often lack the power density required to effectively power these devices under typical indoor lighting conditions.
Solution
Ambient Photonics develops dye-sensitized solar cells (DSSC) optimized for harvesting energy from low-intensity ambient light. These photovoltaic cells convert indoor light into usable power, eliminating or significantly reducing the need for batteries in connected devices. Ambient's technology achieves up to three times greater power density compared to conventional amorphous silicon solar cells, enabling self-powered operation for a wide range of devices. The company's cells can be seamlessly integrated into various product designs, offering a sustainable and convenient power source for the IoT and consumer electronics industries. Furthermore, Ambient offers bifacial solar cells capable of harvesting light from both sides of the cell, boosting efficiency and enabling more powerful electronics.
Target Audience
Ambient Photonics primarily targets IoT device and electronics manufacturers in the smart home, consumer electronics, and industrial sectors seeking sustainable and battery-free power solutions.
