I have 2 solar cells connected in series to give me an ouput of 7.2v (3.6v X 2) and a current of 70 ma. I am building a solar charger for various handheld devices like my PDA, ipod, and cel phone. These require 5v to my USB connector to charge them which I get by putting in a 5v regulator. Is there anyway I can increase the ma's without adding solar cells in parallel? In other words, can I convert the excess volts I have into increased current via circuitry?
Thanks,
