Theory of the solar cell:

Solar cell is a device that responds to light and can convert light energy into electricity. There are many kinds of materials that can produce photovoltaic effect, such as mono-crystalline silicon, poly-crystalline silicon, amorphous silicon, gallium arsenide, selenium indium copper, etc. Our products use mono-crystalline silicon. When light shines on the surface of solar cells, some photons are absorbed by silicon materials; The energy of photons is transferred to silicon atoms, making electrons transition and become free electrons. They gather on both sides of the p-n junction to form a potential difference. When the external circuit is connected, under the action of this voltage, a current will flow through the external circuit to produce a certain output power.
