Apple 'Evaluating' Solar Cell Vendors for Future Products?
Samsung and Apple have been evaluating the possible niche market for solar-powered consumer products and considering the inclusion of Taiwan-based solar firms in their respective supply chains. However, according to Taiwan-based solar firms, these niche markets will need a longer time to develop.Apple has expressed interest in solar power for a number of years, with a patent application published in 2008 discussing the possibility of placing solar cells underneath a mobile device's screen. A more recent one discussed building solar cells into the external surface of an iPod-like device and integrating a power management system to balance battery and solar power generation to compensate for changes in light input due to environmental factors or certain panels being obscured by the user's hand.

Even more recently, The Wall Street Journal reported that Apple is working on "a new way of charging" for next year's iPhone. Speculation has naturally centered on some form of wireless induction charging given that technology is already mature enough to have made it into the consumer market, but at the very least Apple seems to be seriously considering alternatives to traditional power production mechanisms for its future devices.
