Element For Solar Cells Ocean Floor Mining

Most solar cells are a few square centimetres in area and protected from the environment by a thin coating of glass or transparent plastic because a typical 10 cm 10 cm 4 inch 4 inch solar cell generates only about two watts of electrical power 15 to 20 percent of the energy of light incident on their surface cells are usually combined in series to boost the. Solid frozen deposits of methane gas found on the ocean floor name two ways to conserve fossil fuels so they exist for a longer time. A solar cell or photovoltaic cell is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect which is a physical and chemical phenomenon.
