How cool would it be use your iPhone and never have to hook it up to a phone charger? According to a Forbes article, that might very well be within the realm of possibility. Apple has filed a patent to place solar cells on portable devices.
The iPhone could have photovoltaic cells placed underneath the LCD multi-touch screen, maximizing the surface area for the cells to gather sunlight. The patent filing said the LCD could display the solar cells performance alongside the battery information.
While some patents never make the light of day, this would be a welcomed addition to the iPhone in my opinion. The only downside is that you would have to leave your iPhone on a table or window seal to take advantage of the solar cells. That small detail could leave many iPhone toting users to accidentally leave their phone behind. Sound off in the comments your thoughts on this idea!
