The ideal quantum efficiency graph has a square shape, where the QE value is fairly constant across the entire spectrum of wavelengths measured.
42.
Resistive losses are predominantly accounted for by the fill factor value, but also contribute to the quantum efficiency and V OC ratio values.
43.
Another advantage of 3CCD over a Bayer mask device is higher quantum efficiency ( and therefore higher light sensitivity for a given aperture size ).
44.
However, phosphorescent OLEDs generate light from both triplet and singlet excitons, allowing the internal quantum efficiency of such devices to reach nearly 100 %.
45.
This was done to develop of device with a quantum efficiency of 68 % and a fill factor of 68 % grown by molecular beam epitaxy.
46.
The active circuitry in CMOS pixels takes some area on the surface which is not light-sensitive, reducing the quantum efficiency of the device.
47.
The effectiveness of a photocathode is commonly expressed as quantum efficiency, that being the ratio of emitted electrons vs . impinging quanta ( of light ).
48.
Such structures may provide a means to improve the quantum efficiency of DSSCs in the red region of the spectrum, where their performance is currently limited.
49.
The type of cathode ( CsTe ) assures sensitivity from longward of Lyman ? to the atmospheric limit with a peak quantum efficiency of approximately 10 %.
50.
Quantum efficiency is most usefully expressed as a " spectral " measurement ( that is, as a function of photon wavelength or energy ).
