How Do Solar Panels Work?

Solar panels are large, flat devices made up of solar cells that convert sunlight into electricity. Each cell, composed of silicon, acts as a semiconductor. When sunlight hits the cells, it energizes electrons, causing them to flow and generate electricity. The cells are structured in layers, with p-type and n-type silicon creating a barrier that electrons cross when activated by sunlight, producing an electric current.
