[PDF Version]In the circuit above, the current from the solar cell flows through D1 to charge the Li-ion battery. When there is less sunlight, the higher voltage from the battery cannot flow back to the solar cell. Because there is a D1 blocking it, the current can flow only one way. The energy in the battery is stored and gradually increases until it is full.
