The solar cells that you see on calculators and satellites are also called photovoltaic pv cells which as the name implies photo meaning light and voltaic meaning electricity convert sunlight directly into electricity a module is a group of cells connected electrically and packaged into a frame more commonly known as a solar panel which can then be grouped into larger solar . A photovoltaic pv cell commonly called a solar cell is a nonmechanical device that converts sunlight directly into electricity some pv cells can convert artificial light into electricity photons carry solar energy sunlight is composed of photons or particles of solar energy these photons contain varying amounts of energy that . Inventing a new solar technology that can compete commercially with todays solar cells is difficult given existing deployment methods but a transparent photovoltaic pv cell would change the rules of the game it could be deposited on any surface without obscuring the look of the underlying material you can have zebra stripes or elephant footprints or whatever you want underneath . The photovoltaic effect is a process that generates voltage or electric current in a photovoltaic cell when it is exposed to sunlightthese solar cells are composed of two different types of semiconductors a p type and an n type that are joined together to create a p n junctionby joining these two types of semiconductors an electric field is formed in the region of the junction as
