Harvesting Artificial Light

Mar-18-19 Organic solar cells able to harvest ambient indoor lighting could one day see us charging our devices with our lamps.

The technology is being developed by a team from Kyushu University, who altered organic photovoltaics (OPVs) to absorb artificial light. In tests, a four-inch square array of the altered OPV panels was able to produce 4.2 volts using ambient artificial lighting, though the power was in the milliwatt range and too low for standard use. However, the team believes the emerging technology will improve, and could have important applications as the Internet of Things expands and increases its power needs.
