Photovoltaic (Solar Cell) is the invention-electronics generated as a device for changing the solar energy into electrical energy by a leading semiconductor, such as Silicon which is inexpensive and easily discover on the surface of the Earth and through the scientific process to produce pure cell panels. When the light against on the cell panels the rays of light with particles of energy called the photon (Proton), will transfer energy to electrons (Electron) in the semiconductor until there is enough energy to jump out of the gravity of the atom (atom) and mobility and move freely, so when electrons move it will make the direct electric current . The characteristics of electricity from solar cells are found with highest power efficiency during the daytime, which is consistent and appropriate to bring solar power to solve applied problems of shortage of power during the daytime.
Photovoltaics (PV) is the name of a method of converting solar energy into direct current electricity using semiconducting materials that exhibit the photovoltaic effect
