Russian scientists have created a solar panel powered by diffused office lighting (4 photos)

The life of a modern person is impossibleimagine without a smartphone. These are entertainment and work, government and banking services, monitoring health indicators and a photo album, remote shopping and watching movies. However, the devices require a constantly charged rechargeable battery, which for design reasons has an extremely limited capacity. Therefore, timely recharging of batteries, carried out either from the network through charging, or from a portable Power Bank, becomes an urgent problem.

However, both of these options require separategadgets that take up a lot of space and have additional mass. Russian researchers offer an elegant and practical solution to the problem of continuous wireless charging of smartphones using solar cells that use even dim office light. For these purposes, NUST MISIS experts have proposed ultra-thin solar cells in the form of a sticker that can be glued to a smartphone case and completely get away from bulky chargers.

When working on the InPOWER project, Russiansused the already known scheme with solar cells on covers. However, traditional designs use silicon cells that require direct sunlight. Innovators from the Russian NUST MISIS suggested using perovskites instead of silicon, the absorption coefficient of solar energy of which is 2 times higher than that of silicon cells existing on the market. Moreover, such elements can work from ordinary lighting in office premises.

According to the developers, for normal operationA Wi-Fi network will require a perovskite solar cell with an area of ​​only 5 square centimeters, and for transmission via Bluetooth - 12 square centimeters. In this case, the element is only under office lighting. Another advantage, scientists call the ability to print elements on 3D printers, which reduces production costs by 50%.

Work on the InPOWER project made it to the finalcompetition "Innovator of Moscow", organized by the mayor's office of the capital. The creators of compact and cost-effective office solar cells are planning to obtain certifications for their products and to launch pilot consumer products that do not require plugs and wires.
