photoelectric cells

Photoelectric cells, also known as solar cells, are devices that convert light energy into electrical energy. They work by absorbing sunlight, which excites electrons in the cell’s material—usually silicon—creating a flow of electric current. When sunlight hits the cell, it releases electrons, generating electricity that can be used to power devices or feed into the electrical grid. These cells are fundamental to solar power technology, providing a clean and renewable source of energy by directly transforming sunlight into usable electricity through the photoelectric effect.
