    That's very easy , thanks for photos too,.. but i think you should put IC 7805 (voltage regulator) to regulate voltage because for many phones' battery 5.5 volts may be high !!

    its really nice project but i think u should add 5v regulator in it.:)

    WOW! Thats definitly nothing you should connect your phone to!
    5.7V is too much for many charging logics and it might ruin your cellphone.

    In addition, many phones require a minimum current supplied, which can not be guaranteed when using direct sunpower.

    Its far better to use a regulated voltage to charge a cellphone, also you should buffer the energy to stabilize the voltage and prevent a permanent on/off when clouds hide the sun.

    This is what i did: Article
    Its a charging controller with LiPo packs, charging over USB or Solar Panel and giving the energy to any USB-Device plugged in when its needed, not only when there is sunlight.

    Although the CD-Case-Panel looks nice, its not recommended to use.

    I think you meant solar panel not battery. It's a neat idea

    Right, sorry for that ;]

    Sounds nice and simple! Where do you get a solar battery? Is it hard to hook the USB to the solar battery?

    It's not hard ;)

    Mobile phones are picky when it comes to the charging voltage. Also, the charging current is definitely bigger than your solar cells. I wouldn't use it on my Iphone. Hint: use them without that plastic lid on. The charging will be shorter.
