A solar cell works by converting sunlight into electricity through the photovoltaic effect. It consists of a thin semiconductor material, usually silicon, which absorbs photons from sunlight. When the photons strike the semiconductor material, they transfer their energy to the electrons in the material, causing them to become excited and move freely. This creates a flow of electrons, known as an electric current. The solar cell contains two layers, one with excess electrons (n-type) and the other with a deficiency of electrons (p-type), creating an electric field. As the excited electrons move towards the p-n junction, the electric field forces them to move in one direction, resulting in a usable electric current. This current can be harnessed and used to power various devices or stored in batteries for later use.
A solar cell works by converting sunlight into electricity through the photovoltaic effect. When sunlight hits the solar cell's surface, the photons (light particles) transfer their energy to the electrons in the semiconductor material within the cell. This energy allows the electrons to break free from their atoms and create an electric current. The separated electrons then flow through the cell's electrical circuit, generating usable electricity.
