Solar Powered Cell Phone In The Works

Researchers at German's Fraunhofer Institute are working on a solar powered cell phone by using device-integrated, high-efficiency solar cells that offers a module efficiency rate of 20%. This allows the cell phone to remain continuously powered up as long as it receives sufficient sunlight (about 2 hours per day), otherwise it can charged using conventional means. Fraunhofer-Gesellschaft is an alliance of more than 50 research institutions, mostly in Germany, that pool their research and collaborate on innovative technology. The Institute has demonstrated a working model of the phone, see this page for more information. :: Story via Personal Tech Blog
