A high efficiency silicon photovoltaic concentrator cell that employs light trapping techniques and point-diffused contacts on the rear surface for current collection.
Industry:Energy
A metric unit of energy or work; 1 joule per second equals 1 watt or 0.737 foot-pounds; 1 Btu equals 1,055 joules.
Industry:Energy
The annual solar savings of a solar building is the energy savings attributable to a solar feature relative to the energy requirements of a non-solar building.
Industry:Energy
A region of transition between semiconductor layers, such as a p/n junction, which goes from a region that has a high concentration of acceptors (p-type) to one that has a high concentration of donors (n-type).
Industry:Energy
A photovoltaic (PV) generator junction box is an enclosure on the module where PV strings are electrically connected and where protection devices can be located, if necessary.
Industry:Energy
The positive electrode in an electrochemical cell (battery). Also, the earth or ground in a cathodic protection system. Also, the positive terminal of a diode.
Industry:Energy
A semiconductor device with a junction and a built-in potential that passes current better in one direction than the other. All solar cells are junction diodes.
Industry:Energy
A material used to make photovoltaic cells, which consist of many crystals unlike single-crystal silicon.
Industry:Energy
A standard unit of electrical power equal to 1000 watts, or to the energy consumption at a rate of 1000 joules per second.
