I would like to charge my iphone through solar energy, but i need to know a couple of things:
. What should I do to convert the solar energy into energy delivered through the usb?
. Where can I fine cheap and flexible solar cells?
Sorry, I don't know where to start.
You can do all you want by shopping.
You can try ebay www.ebay.com
and amazon www.amazon.com
both of which will have a number of sellers of this sort of thing.
What country are you in?
Doing it your self makes little sense in most cases.
if you do want to make your own solar to iPhone charger then having a switching power supply in the middle may be a good idea.
Here's quite a good way to make one yourself. Solar Minty Boost
Basic Minty Boost here.
