ITMO researchers have created a surface that can turn normal glass into a smart surface. This technology can be used in the production of AR screens that equip users with additional information about what is happening around. The surface will also be able to convert solar energy into electricity. The research has been published in Laser & Photonics Reviews.
The innovative solution of the researchers is a thin film based on halide perovskites, semiconductor materials with extraordinary optical and electronic properties. These films are affordable to produce, they are used to create LEDs and solar cells with efficiency factors exceeding traditional technologies. The perovskites used in the project can transmit around a half of the light distinguished by the human eye. However, they reflect too
