Light can be absorbed by certain materials to release electrons, creating a voltage. This is known as the photovoltaic effect, and it was first discovered in 1839. Therefore the method of converting energy from sunlight and turning it into electricity is known as Photovoltaics. Photons of light excite the generated electrons and they jump to a conduction band within the solar cells. Direct current electricity is produced. Photovoltaics (PV) is the method by which scientists harness the sun’s radiation and solar PV panels utilize photovoltaic material to create a renewable and abundant energy source.
