/diy/ - Do It Yourself

Has anyone had a play with these very cheap solar cells? they are under 10c ea in quantities of only 100, and even cheaper in larger amounts. I've had a good look at reviews and videos of them, and they seem to match the rated output (short circuit, but sellers mention this in the specs). Even under load, they are still very good.
My only concern is housing them, since they are wafer thin (0.25mm) and extremely fragile. Proper solar resin is expensive, and it ends up being cheaper to just buy premade.
The only thing i can think of for these, would be to secure them to something rigid, like plastic board, and only put them out when you need to use.

For those wondering, they are .5v cells @ ~400mA short circuit. 50mm * 20mm * 0.25mm. Also worth noting, they work out to be roughly $1\Watt, so only good for small or custom shaped panels.

Any ideas, opinions, etc on these?
