- Company Profile:
A measure of the flow of current (in amperes) over one hour; used to measure battery capacity.
Industry:Energy
An electrically charged atom or group of atoms that has lost or gained electrons; a loss makes the resulting particle positively charged; a gain makes the particle negatively charged.
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
The direct, diffuse, and reflected solar radiation that strikes a surface. Usually expressed in kilowatts per square meter. Irradiance multiplied by time equals insolation.
Industry:Energy
An instrument that monitors current with time. The indication is the product of current (in amperes) and time (in hours).
Industry:Energy
Guidelines for the assessment of photovoltaic power plants, published by the Joint Research Centre of the Commission of the European Communities, Ispra, Italy.
Industry:Energy
A plate for a battery in which active materials are held in a perforated metal pocket.
Industry:Energy
Semiconductor material that is left intrinsic, or undoped so that the concentration of charge carriers is characteristic of the material itself rather than of added impurities.
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 graphical presentation of the current versus the voltage from a photovoltaic device as the load is increased from the short circuit (no load) condition to the open circuit (maximum voltage) condition. The shape of the curve characterizes cell performance.
