A silicon solar cell is a photovoltaic cell made of silicon semiconductor material. It is the most common type of solar cell available in the market. The silicon solar cells are combined and confined in a solar panel to absorb energy from the sunlight and convert it into electrical energy.
This property of silicon is often used in light-sensitive devices to ascertain the presence of light and calculate its intensity. It also comes in handy to understand the internal mechanisms of these devices. The excellent photoconductivity of silicon makes it an excellent choice for solar cells.
A silicon solar cell works the same way as other types of solar cells. When the sun rays fall on the silicon solar cells within the solar panels, they take the photons from the sunlight during the daylight hours and convert them into free electrons. The electrons pass through the electric wires and supply electric energy to the power grid.
