What is Photoelectric Effect?
When light hits a metal surface it can produce an electric potential. This phenomenon is called a photoelectric effect. This concept is used to generate electricity directly from the energy of light. Solar Panels use this concept in full effect to charge the batteries of the calculators, as a source of power supply in traffic lights and also used as the source of light to light up our homes. Solar energy is one of the reliable sources of energy and it is the largest source of energy on planet earth. The use of solar energy helps in cutting down power costs and to have a healthier environment.
