No, the technology isn't there.
Those garden lights charge up all day and give a tiny bit of light at night.
Mobiles and tablets suck a lot more juice. A lot more. And the amount of charge that can be supplied by solar cells just isn't anywhere near enough, at least no in the footprint of a mobile.
You can get solar chargers - they're relatively large (several times larger than mobiles), you leave them in the sun all day and they charge up an internal rechargeable. Then you can use them to charge up your mobile overnight. Great for camping trips or holidays away where there's plenty of sun.
When solar cells become more efficient, then they'll be practical. But at the moment, not possible or practical.
