    Hi guys,

    i want to make a solar charger for cell phones as my final year project. But i really do not know how to go about it. In this semester, we have to come with an idea and present a report and in the next we have to build it. how do i start on it? are there any other ideas for the project? i want to build something that is easier to build and implement.

    Thanks,

    Start with a solar panel whose open-circuit bright-sun output voltage is at least twice the cell phone's internal battery voltage....

    The charger circuit for a cell phone is already inside the phone.
    You can use a battery charger IC for charging spare batteries.
