In the near future, smartphones that don't need wall plugging may be available. All you need to do is expose its screen to direct sunlight, and poof! Your battery instantly gets charged.

This technology is what scientists from the Michigan State University is trying to develop. The researchers have invented an almost transparent solar power collector that they believe can be the future of powering smartphones.
The system is called luminescent solar collecting materials, or simply LSC. It is an inexpensive thin plastic sheet that can absorb light and re-emit it in the form of energy. They are currently found in infrastructures where windows are covered by the colored versions. Currently, the color in these LSCs gives them a higher efficiency in converting solar power to reusable energy.
One of the researchers, Richard Lunt, had admitted that the transparent LSCs have a poor 1% in its solar conversion efficiency ratio. But they are still trying to upgrade its material for it to be more applicable to industrial uses.
