An iPhone with integrated solar cells may be quite a ways off, so in the meantime Solar Arcadia’s solar-powered cases are your best option. The cases are available in SideFlip and Leather Flip models and offer a bit of extra protection for your handset.

They feature a solar panel so that your phone can enjoy at least a few more minutes of life while you’re out in the sunlight. Each case is constructed from ABS sheepskin and comes in a trio of colors. Red, white or black (The Leather Flip is only available in black).
