- Company Profile:
A method of preventing oxidation of the exposed metal in structures by imposing a small electrical voltage between the structure and the ground.
Industry:Energy
May be used for photovoltaic array wiring if sunlight resistant coating is specified; can be used for interconnecting balance-of-system components but not recommended for use within battery enclosures.
Industry:Energy
Current carriers (either free electrons or holes) that are in excess in a specific layer of a semiconductor material (electrons in the n-layer, holes in the p-layer) of a cell.
Industry:Energy
The cutting of a grid pattern of grooves in a semiconductor material, generally for the purpose of making interconnections.
Industry:Energy
The ratio of a photovoltaic cell's actual power to its power if both current and voltage were at their maxima. A key characteristic in evaluating cell performance.
Industry:Energy
The point on the current-voltage (I-V) curve of a module under illumination, where the product of current and voltage is maximum. For a typical silicon cell, this is at about 0.45 volts.
Industry:Energy
A single unit of an electrochemical device capable of producing direct voltage by converting chemical energy into electrical energy. A battery usually consists of several cells electrically connected together to produce higher voltages. (Sometimes the terms cell and battery are used interchangeably). Also see photovoltaic (PV) cell.
Industry:Energy
May be used within battery enclosures and for interconnecting balance-of-systems.
Industry:Energy
Means of a power conditioning unit that automatically operates the photovoltaic generator at its maximum power point under all conditions.
Industry:Energy
A battery with a captive electrolyte and a resealing vent cap, also called a valve-regulated battery. Electrolyte cannot be added.
