What are Photovoltaics?
Definition of Photovoltaics Cells
Photovoltaic cells produce usable electric current, using energy in the form of photons. These cells are commonly known as solar cells or PV.
Photovoltaic Cells Produce Direct Current
These cells form an electric current in which the electrons go in a circular pattern, and do not alternate direction. This is simlar to battery power, as opposed to a power plant. This direct current can be converted to alternating current for home or industrial use.
Often, cells are not found alone but are grouped together in series, to form what is called a solar array. These are generally placed under glass or plastic for protection from the weather. When hooked in series, a lot more electricity is generated.
