Motorola is up to new tricks with its recent patent for a cell phone display that doubles as a solar cell. Apparently, the screen will be able to charge a cell phone's battery when the display is exposed to the sun. Though external solar-powered battery chargers are a reality, this is the first concept we've seen for a cell phone with an integrated solar panel. It's doubtful the phone would get all its juice from the sun. Rather, sunlight probably would power the handset while it's away from an electrical outlet. We have no idea which phone model Moto would outfit with the technology, but it appears a Razr Maxx Ve showed up in the patent filing.
