An electrical current from the solar cell charges the battery, and some current also goes to the control, turning the LEDs off. Simple Solar Li-ion battery charger circuit. This is the simplest Solar Li-ion battery circuit, consisting of only three components:
Using the solar light IC all you need is the solar IC, an inductor, and the ultra-bright LED to make the circuit. Add the battery and the solar cell and you have a solar light. I haven''t had much luck finding the datasheet for the solar light ICs and the three I found are not in English. That aside the inductor controls the power to the LED.
The LED comes on when it gets dark and the solar panel is no longer able to charge the battery, so there has to be some sort of control circuit inside to do this. Inside the example I deconstructed was a single 1.25 volt 100 mAh AAA NiCd cell and a small PCB with the LED, a 220 uH inductor, and a four pin voltage boosting integrated circuit ...
