Apple Solar Patent

A recently surfaced patent, spotted by Patently Apple, shows that Apple employees filed a patent to embed solar cells below the touchscreens of handheld devices.

Creating a single "stack" that combines the sensors for a multitouch screen and solar cell frees up more surface area, according to the patent description. The patent was filed in Fall 2008, and calls for the use of "light channels" to direct light to a solar cell beneath a touch screen, potentially using a parabolic reflector.
