21Organic light-emitting diode — Demonstration of a flexible OLED device A green emitting OLED device An …
22Incandescent light bulb — The incandescent light bulb, incandescent lamp or incandescent light globe is a source of electric light that works by incandescence, (a general term for heat driven light emissions which includes the simple case of black body radiation). An… …
23Electrical efficiency — The efficiency of an entity (a device, component, or system) in electronics and electrical engineering is defined as useful power output divided by the total electrical power consumed (a fractional expression), typically denoted by the Greek… …
24LED anchor light — A LED anchor light is a newer type of an already existing marine signaling light known as an anchor light , defined by international regulations as a 360 degree white all round light with a given range of one NM (Nautical Mile), two NM, or three… …
25Quantum efficiency — (QE) is a quantity defined for a photosensitive device such as photographic film or a charge coupled device (CCD) as the percentage of photons hitting the photoreactive surface that will produce an electron–hole pair [… …
26Energy conversion efficiency — Output energy is always lower than input energy …
27Fuel efficiency in transportation — This page describes fuel efficiency in means of transportation. For the environmental impact assessment of a given product or service throughout its lifespan, see life cycle assessment. Caveats Comparing Fuel efficiency in transportation is a bit …
28Quantum efficiency of a solar cell — Quantum efficiency (QE) is the ratio of the number of charge carriers collected by the solar cell to the number of photons of a given energy shining on the solar cell. QE therefore relates to the response of a solar cell to the various… …
29Static light scattering — is a technique in physical chemistry that measures the intensity of the scattered light to obtain the average molecular weight Mw of a macromolecule like a polymer or a protein. Measurement of the scattering intensity at many angles allows… …
30Photosynthetic efficiency — The photosynthetic efficiency is the fraction of light energy converted into other forms of energy for use. Trees convert light in to chemical energy through the process of photosynthesis with a photosynthetic efficiency of approximately 0.2 0.5% …
