A dream can be true, no more ever to charge your smartphone!
Researchers at the University of campridge, IEEE Fellow Arokia Nathan are working on that goal.
To reach that goal the team built a prototype device that converts ambient light into electricity using an array of solar cells made of thin film hydrogenated amorphous silicon thats designed to sit within the smartphone screen.
Only 36 percent of a OLED screen is projected out of the front of the screen!.
Nathan and his collaborators at his Canadian firm IGNIS Innovation set out to harness this wasted light by putting thin-film PV cells around the display’s edges as well.
At this time the average efficiency of this combination is about 11 percent and peak efficiency of 18 percent.
If the PV array converts 5 percent of ambient light to electricity, the energy-harvesting system can generate as much as 165 microwatts per square centimeter under the right lighting conditions.
