- Company Profile:
A metal plate, usually lead or lead compound, immersed in the electrolyte in a battery.
Industry:Energy
A measure of the flow of current (in amperes) over one hour; used to measure battery capacity.
Industry:Energy
A semiconductor photovoltaic device structure in which the junction is formed between a p-type layer and an n-type layer.
Industry:Energy
An instrument that monitors current with time. The indication is the product of current (in amperes) and time (in hours).
Industry:Energy
A plate for a battery in which active materials are held in a perforated metal pocket.
Industry:Energy
The angle that a ray of sun makes with a line perpendicular to the surface. For example, a surface that directly faces the sun has a solar angle of incidence of zero, but if the surface is parallel to the sun (for example, sunrise striking a horizontal rooftop), the angle of incidence is 90°.
Industry:Energy
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
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
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.
