Open-circuit voltage
Energy; Energy efficiency
The maximum possible voltage across a photovoltaic cell; the voltage across the cell in sunlight when no current is flowing.
Diffusion length
Energy; Energy efficiency
The mean distance a free electron or hole moves before recombining with another hole or electron.
Ignition point
Energy; Energy efficiency
The minimum temperature at which combustion of a solid or fluid can occur.
Flashpoint
Energy; Energy efficiency
The minimum temperature at which sufficient vapour is released by a liquid or solid (fuel) to form a flammable vapor-air mixture at atmospheric pressure.
Air
Energy; Energy efficiency
The mixture of gases that surrounds the earth and forms its atmosphere, composed of, by volume, 21 percent oxygen, 78 percent nitrogen.
Spectral irradiance
Energy; Energy efficiency
The monochromatic irradiance of a surface per unit bandwidth at a particular wavelength, usually expressed in Watts per square meter-nanometer bandwidth.
