Japanese electronics giant Sharp is poised to launch its first solar-powered mobile phones in its home market this summer, according to local press reports.
Mobile phone operator KDDI Corp confirmed yesterday that it is to start offering Sharp's "Solar Phone SH002" from next month, which features a polycrystalline silicon solar cell module on the back of the handset.
Makoto Takahashi, general manager of the consumer service and product sector at KDDI, told the Tech-On news website that the launch made the company "the only mobile-phone carrier who can offer a solar-powered handset by this summer".
Rival mobile phone operator SoftBank Mobile is expected to offer an alternative solar-powered Sharp phone later this summer called the "Solar Hybrid 936SH".
Details about both models are sketchy and Sharp is yet to disclose the conversion efficiency of the solar cells it is using. But according to reports, just 10 minutes of charging is expected to provide the battery with enough energy to make a one-minute voice call and operate the phone for roughly two hours in standby mode, raising the prospect of rarely, if ever, having to charge the phone from the mains.
The new phones establish Sharp as one of the forerunners to develop a mainstream solar-powered handset.
It is likely to face competition from Samsung, which debuted its first solar-powered handset at the Mobile World Congress Show in Barcelona earlier this year, as well as a raft of consumer electronics firms who are understood to have projects under way to develop solar-powered handheld devices.

Mobile Battery On Energy
this is very true fact that we can operate our battery by the use of all energy not only solar energy b'coz if we use only solar energy then it only works in the day time and in the cold atmosphere when there is no solar energy comes on the energy then these mobiles can not get the solar energy to get charged for more time but if we make the battery in a way to absorb all sort of energy available near to us like heat energy , sound energy , mechanical and wind energy when the particles of these four major energy stored in the battery to absorb the energy to charged the battery for 24 hrs
