Why Solar Panels Don't Charge at Night

We have all seen solar panels installed on rooftops. They produce electricity from sunlight during the day. But have you ever wondered whether if you put a torchlight on a solar panel at night, it is charged or not? The answer is no, the torchlight does not charge the solar panel. But why does this happen? This question seems easy to hear, but the answer is related to a special thing in science. Let's know about it. First of all, it is important to know how the solar panel works, so tell you that there are small parts inside the solar panel called solar cells. These cells are made of a special material called silicon. When sunlight falls on these cells, small particles of light called photons hit the electrons inside the silicon. From this collision, the electrons flow out of their place and create electricity. But to remove the electrons from the solar panel, it must be very powerful.
