An exception is when a diode reverse-conducts, either by accident (breakdown of a normal diode) or by design (breakdown of a Zener diode, photo-current of a photodiode). Source: Internet

A PIN photodiode can also detect X-ray and gamma ray photons. Source: Internet

Dark current must be accounted for by calibration if a photodiode is used to make an accurate optical power measurement, and it is also a source of noise when a photodiode is used in an optical communication system. Source: Internet

; Dark current : The current through the photodiode in the absence of light, when it is operated in photoconductive mode. Source: Internet

In further processing, a photodiode is used to transform the optical field into an electric current, so the information is changed back into its original state. Source: Internet

Otherwise a spectrometer as detector for the power is needed instead of a photodiode which has not a selective wavelength dependence. Source: Internet
