Rays of sunlight hit the solar panel and are absorbed by semi-conducting materials such as silicon. Â Photovoltaic cells are usually made from silicon, an excess material that constitutes more than 28 percent of the Earth's crust. These cells are created by bonding two wafers of silicon that are connected to metal wires The top water is silicon is thin and bottom is thicker the wafers produce electricity as absorb solar radiation hope it helps
