There are three main types of metals used in solar panels: silicon, copper, and silver. Silicon is the most abundant element on Earth's crust and is widely used in various industries due to its. . While much of solar panels are made up of minerals you can easily call to mind — like aluminum, copper, and silicon — others you won't come across in your daily life. These cells are typically made of silicon, which is a semiconductor material that can absorb photons from sunlight and release electrons to create an electrical current. How do Solar Panels Work?. Solar panels, also known as PV modules, are the most recognizable component of a PV system.
