Most of us start smiling when the sun’s rays start trickling on our faces – this isn’t shocking because scientists have proved that the sun can improve our moods and boost energy. Isn’t it wonderful if this sun can keep your phone alive without an outlet or charging wire?

Ubiquitous Energy- an MIT spinoff company- has recently invented a coating which transforms cellphone surfaces into solar panels. Solar panels are devices that collect photons and convert them into electricity. These panels are dark because darker colors absorb more heat while lighter colors reflect wavelengths of light. Ubiquitous Energy (UE) created a coating made of organic molecules that absorb the sun’s ultraviolet and infrared rays. Since ultraviolet and infrared rays are not in the visible light range, the coating appears clear to humans! The founder of UE, Michael Barr, believes the company will be able to develop handheld tech applications to surpass 10% efficiency. As interest and demands increase, UE is heading towards creating more breakthroughs in our technologically progressing world. Looking forward to seeing more from UE!


Transparent solar cells are here, but they won't see the light of day for years
