Customer ServiceIn 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.
An electrical current from the solar cell charges the battery, and some current also goes to the control, turning the LEDs off. This is the simplest Solar Li-ion battery circuit, consisting of only three components: Nowadays, we prefer to use Li-ion batteries over other types of batteries because they have higher efficiency.
The input to the circuit can be anywhere between 10 and 40V, which becomes the ideal range for the solar panels. The key features of the IC includes: In order to generate accurate PWMs, the IC includes a precise 5V reference made by using bandgap concept which makes it thermally immune.

Working Principle: The working of solar cells involves light photons creating electron-hole pairs at the p-n junction, generating a voltage capable of driving a current across a connected load.
For safety tests of the cells, “UL” requires either an additional diode, or a resistor, limiting the current to a safe level of 4 mA (for all cylindrical CR...A(A) lithium mass cells). It should be noted that the value of the resistor has to be calculated using the higher power supply voltage – not the battery voltage.
