A PV Cell or Solar Cell or Photovoltaic Cell is the smallest and basic building block of a Photovoltaic System (Solar Module and a Solar Panel). These cells vary in size ranging from about 0.5 inches to 4 inches. These are made up of solar photovoltaic material that converts solar radiation into direct current (DC) electricity.
The batteries have the function of supplying electrical energy to the system at the moment when the photovoltaic panels do not generate the necessary electricity. When the solar panels can generate more electricity than the electrical system demands, all the energy demanded is supplied by the panels, and the excess is used to charge the batteries.
But ultimately, all photovoltaic cells perform the same function. A photovoltaic cell harvests photons from sunlight and uses the photovoltaic effect to convert solar power into direct current electricity. The photovoltaic cells contained in a PV module transmit DC electricity to an on-grid, off-grid, or hybrid solar system.
