OK, it looks like an nice concept. However, the numbers don’t add up. Batteries that size contain ~3-4 Ah. A solar cell of that size wrapped around it will deliver 4mAh on a lucky sunny day. So you only need to put it in the sun for 1000+ hours to recharge it. Except that the battery will discharge itself two times over in the same timeframe.
What is wrong with the concept of a separate charger? You could buy green electricity if you feel so inclined.

With a capacitor and a way to bleed off excess charge these should work out great for smaller, travel items and the like.

I guess that warning of leaving batteries out to exposed sunlight does not apply anymore! lol

I agree. Batteries don’t have enough heavy metals in them already.
