Hello,
I have been planing on making a solar cells powered charger lately. My plan is that I will be using two 10V 30mA solar cells in a parallel circuit, I will be connecting a Schottky diode at the output and it will directly be connected to my cellphone battery which has the specification of 3.7V 1500mA through a usb connector.
My main question is, do I have to lower/regulate the voltage of the output so that it will not "burn" my battery and but if so, what kind of regulator should I use for my plan (please suggest me an simple method as I might not be able to provide all the necessary needs for a more complicated project)
I would consider myself as a beginner in solar cells, so I hope the best from you guys!
P.S.
The battery type is a Li-Polymer battery.
