LG solar-powered handset

LG Electronics' solar-powered handset, showcased at MWC 2009, has its solar power system embedded onto the battery cover to conveniently harness the sun's limitless and pollution-free energy.

By simply pointing the phone's solar panel at natural light, the panel will convert solar energy into electricity without needing to be plugged in. Exposing the panel to the sun for 10 minutes will give the phone enough power for a three-minute call. If left in natural light for long periods, the solar panel creates enough standby power to power the phone without any charging devices.

LG plans to release this eco-friendly phone in the European market at the end of this year.
