photovoltaic cell

A photovoltaic cell, commonly known as a solar cell, converts sunlight directly into electricity. It is made of semiconductor materials, usually silicon, that absorb photons from sunlight. This absorption excites the electrons, creating an electric current. When many cells are connected, they form a solar panel that can generate significant power. Solar cells are clean, renewable sources of energy, helping reduce reliance on fossil fuels and decrease greenhouse gas emissions. They are used in various applications, from powering homes and businesses to satellites and portable devices.
