Photovoltaics (PV) is the name of a method of converting solar energy into direct current electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon commonly studied in physics, photochemistry and electrochemistry.hotovoltaics are best known as a method for generating electric power by using solar cells to convert energy from the sun into a flow of electrons. The photovoltaic effect refers to photons of light exciting electrons into a higher state of energy, allowing them to act as charge carriers for an electric current.
SOLAR ENERGY EDUCATION. Solar power is clean green electricity that is either created from sunlight or from heat from the sun. Having solar electricity in your home usually means setting up a solar photovoltaic system on your roof. Definition of photovoltaic: Photo = âlightâ and photons = energy particles coming from sunlight; v oltaic = producing a voltage or volts. Abbreviation = PV. Solar energy is a renewable free source of energy that is sustainable and totally inexhaustible, unlike fossil fuels which are finite.
