Charge the battery from the OLED screen

A foggy UK researcher has initially succeeded in creating a solar cell grid that absorbs the light emitted by the OLED screen on a mobile phone to charge the battery. .

According to Extremetech, scientist Arman Ahnood at the heart of nanotechnology London (UK) late last year each made findings that only 36% of the light from the OLED is emitted outside and become "visible " in the eyes of the user, while the rest is completely wasted.

Ahnood has created a solar photovoltaic grid with solar cells for lateral arrangement and at the back of the OLED, able to "collect" the entire light source. emitted from the screen and then "recycled" into electrical energy to charge the battery.

Ahnood's invention actually uses a thin film (including electrical circuits and supercapacitors), which can be easily "glued" to the OLED or LCD screen of a mobile device without creating any. an increase in size as well as light scattering (in the case of placing the film in front of the screen).

Ahnood's latest test results in 11% of the total energy that the transceiver can convert into electricity.

Ahnood and his team have set a goal of redesigning the solution, from design to materials, to 90 percent of the light that can be transferred from OLEDs to battery power.
