What is a solar cell?

Solar cells, also known as photovoltaic cells, are devices that convert sunlight directly into electricity through the photovoltaic effect. They are typically made from semiconductor materials like silicon, which absorb photons from sunlight and release electrons, generating an electric current. Solar cells are the building blocks of solar panels, which are widely used for renewable energy generation in homes, businesses, and utility-scale power plants. Their efficiency and affordability have improved significantly over the years, making solar energy an increasingly popular and sustainable power source.
