Solar-powered cellphones

May 29th, 2007

New Scientist describes two new patents granted to Nokia and Motorola which plan to improve the batteries of our favorite handhelds (see below for tips on how to find a full version of a patent). While Nokia wants to develop self-powered billboards, Motorola is building a liquid crystal display (LCD) that incorporates a solar panel behind the screen of a phone. Other companies have tried to put solar cells behind phones’ screens without success. Motorola says its approach is different because this new LCD will act both as a display and a light collecting device for the solar cell. No date is given about the availability of such a solar-powered phone.
