- This will eliminate the need to carry a charger.
Russian scientists of MISIS presented the project “InPOWER” — a new generation of solar panels that work in diffused light. Such a solar cell can be pasted as a sticker on the smartphone case and completely eliminate wired charging. The dim light of an office lamp will be sufficient for charging.
The National University of Science and Technology “MISiS” is Russia’s primary technological university in the field of steelmaking and metallurgy. It was established in 1918 as a part of the Moscow Mining Academy. In 1930, it became independent.
Smartphones are firmly embedded in our lives, and they are used for literally everything: calls, messages, social networks, navigation on the road, online shopping, listening to music, watching videos, and so on. With increasing functionality, the battery capacity remains quite limited.
Hence, many, including myself, constantly carry a charger and power bank with me. Even though the battery came a long way, there is a need to constantly charge the smartphone.
Additionally, many smartphones have a wireless charging function, but you either need to carry the station with you, which is not always convenient, or search nearby. Those people who live in sunny regions are a little more lucky: they can use special cases with solar silicon cells for charging. However, without direct sunlight, such batteries are almost useless.
Scientists at MISIS have found a way to solve the problem of wireless charging of smartphones. They have developed solar panels that can absorb even dim, scattered light from office lamps. Instead of silicon, perovskites are used, and their absorption coefficient is two times higher than that of analogues on the market.
A perovskite is any material with the same type of crystal structure as calcium titanium oxide, known as the perovskite structure. Perovskites take their name from the mineral, which was first discovered in the Ural mountains of Russia by Gustav Rose in 1839 and is named after Russian mineralogist L. A. Perovski.
As Danila Saranin, head of development, engineer of the laboratory of advanced solar energy at MISIS explains:
“To power a Wi-Fi translator, you will need only 5 cm2 of perovskite solar cells, and for Bluetooth transmission-12 cm2 in dim office lighting. In addition, the technology allows you to print solar panels on printers without expensive production processes and reduce the cost compared to analogues by 50%.”
Danila S. Saranin from the National University of Science and Technology MISIS at Department of Semiconductor Electronics and Semiconductor Physics already has over 23 publications and one of the promising engineers in Russia.
While young scientists have fully developed a modular range of batteries on glass and plastics, the next stage is certification and entering into pilot projects. Eventually, the team plans to create a product that will completely eliminate wires and sockets.
Technology continues to evolve and this invention will eliminate the need to carry a charger everywhere. Therefore, it is one less thing to carry around and a lot of times changes are forgotten and lost in the public places.
