Photovoltaic is everything related to the conversion of light into electrical energy. Photovoltaic panels develop this concept. Photovoltaic cells are devices that convert solar energy into electrical energy. When photons from light energy bump into the cell''s surface, they trigger an electric current moving electrons from one atom to another.
