Ambient Photonics Opens Low-Light Photovoltaic Cell Factory

Facebook Twitter LinkedIn Email
Ambient Photonics has started mass production on low-light photovoltaic (PV) cells at its low-light PV cell factory in Scotts Valley, south of Silicon Valley. According to Ambient, the company's PV cell technology transforms indoor light into energy with 3× more power density than conventional technology. The technology provides power for electronic devices and can also eliminate the need for disposable batteries and reduce carbon emissions of battery-powered devices by as much as 80%, the company said.

Ambient’s proprietary technology combines molecular chemistry and a digitally defined manufacturing process that enables highly scaled production of power-dense PV cells on optically clear glass substrates. Ambient’s finished PV cells combine high indoor light energy density with very low production costs, which the company said enables it to offer its power solutions across a wide range of industries seeking to reduce carbon emissions from their product lines. Ambient said it is initially focused on supporting markets such as consumer electronics, retail, and IoT by powering devices such as remote controls, keyboards and mice, electronic shelf labels, and sensors.

The 43,000-sq-ft California facility, which Ambient said is online less than one year after groundbreaking, will enable the company to produce tens of millions of units per year, and is the first of its kind in the country, Ambient said. The company has established an automated production process at its low-light PV cell factory, using funding from a $48.5 million series A round co-led by Amazon, it said.

In morphological image processing, a series of erosions followed by the same number of dilations.
solar cell
A device for converting sunlight into electrical energy, consisting of a sandwich of P-type and N-type semiconducting wafers. A photon with sufficient energy striking the cell can dislodge an electron from an atom near the interface of the two crystal types. Electrons released in this way, collected at an electrode, can constitute an electrical current.
ambient light
Light present in the environment around a detecting or interpreting device, especially a machine vision system, and generated from outside sources. Such light must be treated as noise by the vision system.
That branch of science involved in the study and utilization of the motion, emissions and behaviors of currents of electrical energy flowing through gases, vacuums, semiconductors and conductors, not to be confused with electrics, which deals primarily with the conduction of large currents of electricity through metals.
power density
In laser welding or heat treating, the instantaneous laser beam power per unit area. This parameter is key in determining the fusion zone profile (area of base metal melted) on a workpiece.
