The photovoltaic or the abbreviation PV is one of the types of systems generating electricity from solar energy. In this method, the use of solar cells, solar panel produces direct electricity from the sun radiation becomes possible. Solar cells of the type of semiconductor that can , i.e., the second element is abundant the Earth's crust are made. When the light of the sun to a cell, photovoltaic sheds, etc. between the two negative electrode and a positive potential difference update, and this has caused a current flow between them. Can be in the category technology, renewable energy ().
