Company Profile:
The voltage at which a charge controller will disconnect the load from the batteries to prevent over-discharging.
Industry:Energy
Concept for providing large amounts of electricity for use on the Earth from one or more satellites in geosynchronous Earth orbit. A very large array of solar cells on each satellite would provide electricity, which would be converted to microwave energy and beamed to a receiving antenna on the ground. There, it would be reconverted into electricity and distributed the same as any other centrally generated power, through a grid.
Industry:Energy
The product of doping a pure semiconductor.
Industry:Energy
The voltage difference between the low voltage disconnect set point and the voltage at which the load will be reconnected.
Industry:Energy
The negative pole or electrode of an electrolytic cell, vacuum tube, etc., where electrons enter (current leaves) the system; the opposite of an anode.
Industry:Energy
Electromagnetic radiation in the wavelength range of 4 to 400 nanometers.
Industry:Energy
A warning buzzer or light that indicates the low battery voltage set point has been reached.
Industry:Energy
A cell barrier established as the interface between a semiconductor, such as silicon, and a sheet of metal.
Industry:Energy
Energy level at which the probability of finding an electron is one-half. In a metal, the Fermi level is very near the top of the filled levels in the partially filled valence band. In a semiconductor, the Fermi level is in the band gap.
Industry:Energy
A sealed battery to which water cannot be added to maintain electrolyte level.
