Why can solar panels generate electricity?

When solar panels are illuminated by light, they can convert light energy into electrical energy, causing current to flow from one side to the other. Solar panels are designed based on this principle. As long as the solar panel is illuminated by sunlight or light, it can generally emit electricity equivalent to 1/10 of the light energy received. In order to minimize light reflection and convert light energy into electrical energy, a solar panel is usually covered with a film to prevent light reflection, making the surface of the solar panel purple. Not so long ago, scientists managed to develop an efficient solar panel. It not only provides electricity during the day, but also electricity at night!
