Solar power for all smart phones? This ingenious idea could soon become a reality for all smart phone users who would no longer have to rely on constantly plugging in to charge up.
Wysips, a French technology company has recently created a thin, transparent, photovoltaic film that fits on top of a smart phone's screen (much like a screen protector) that harnesses energy from the sun and continuously tops off the phone's battery. The company says this solar film can charge a cell phone battery in about 6 hours in constant direct sunlight, taking longer to charge indoors.
