At last, it’s coming. What? Eco-friendly mobile phones. Hopefully. The Fraunhofer Gesellschaft (the largest labs for applied sciences in Germany) has rolled out a prototype sun powered mobile phone.
Sure, this isn’t the ever first solution up to now. Solar panels can recharge your empty battery. And their efficiency increases while decreasing the charging time. Cool, but that doesn’t extend your battery lifespan; that doesn’t make your cellphone more self-sufficient.
So let’s go step further. Instead of charging the battery, what if the battery recharges itself with the sun?… That’s the idea of the Fraunhofer Institute. Researchers have developed a flexible, bendable battery.
The mobile phone, which will be showcased in the upcoming Hanover trade fair, is claimed “to achieve a module efficiency rate of 20 percent using device-integrated, high-efficiency solar cells.” This means “the phone can always stay powered on. A solar-powered PDA would also be capable of operating self-sufficiently.”
