Sciencetech Quantum Efficiency

​

The quantum efficiency (QE) of a device is a measure of its ability to convert incoming photons into electrons or other charge carriers.
For example, a device with a Quantum efficiency (QE) of 50% will produce 50 electrons of signal if it receives 100 photons. QE is critical for  light-detecting devices such as cameras, solar cells, and photodetectors.    Quantum efficiency (QE)    is determined by the wavelength of the photons as well as the characteristics of the device material.    Quantum efficiency (QE)    can be eternal or internal, and it can be described as a function of wavelength or energy.
