Solar cell
- A solar cell is an electronic device that converts the energy of light directly into electricity by the photovoltaic effect.
- The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material. Electrons emitted in this manner are called photoelectrons.
- The solar cell is made up of silicon.
- A solar cell consists of a layer of p-type silicon placed next to a layer of n-type silicon.
- When we connect the n-type and p-type layers with a metallic wire, the electrons will travel from the n-type layer to the p-type layer by crossing the depletion zone and then going through the external wire back of the n-type layer, creating a flow of electricity.
