In reference to solar photovoltaic cell manufacure, a method of growing a large-size, high-quality crystal whereby coils heat a polycrystalline ingot placed atop a single-crystal seed. As the coils are slowly raised the molten interface beneath the coils ...

The volume of a unit weight of a substance at a specific temperature and pressure.

Fabricated as a single structure.

The resistance between metallic contacts and the semiconductor.

A type of building ventilation system that uses fans or blowers to provide fresh air to rooms when the forces of air pressure and gravity are not enough to circulate air through a building.

A vehicle with an engine capable of operating on two different types of fuels.

The region between an n-layer and a p-layer in a single material, photovoltaic cell.

A single photovoltaic device.

The tank of a water heater.

A type of solar photovoltaic device made in a continuous process of pulling material from a molten bath of photovoltaic material, such as silicon, to form a thin sheet of material.

A generator with a single armature coil, which may have many turns and the alternating current output consists of a succession of cycles.

Recombination occurring in the emitter region of a photovoltaic cell.

A type of house that has massive amounts of insulation, airtight construction, and controlled ventilation without sacrificing comfort, health, or aesthetics.

A type of furnace in which fuel is spread, automatically or mechanically, across the furnace grate.

An axail flow fan mounted in a section of duct to move conditioned air.

An empirical measure of the quantity of light. It is based upon the spectral sensitivity of the photosensors in the human eye under high (daytime) light levels. Photometrically it is the luminous flux emitted with a solid angle (1 steradian) by a point so ...
