Pin photodiodes for applications with high sensitivity in sensor technology

Photodiodes are diodes that convert incident light (photons) into an electric current at a p-n junction. This happens due to the photoelectric effect that takes place inside the diode. A photodiode can consist of a wide variety of semiconductor materials, depending on the wavelength of the incident light. The way a photodiode works is as follows:
The incident photons cause an electron-hole pair in the space charge region of a p-n junction. As is usual with a semiconductor, the electrons are accelerated towards the n-side and the holes towards the p-side. These opposing movements increase the electric field strength in the space charge zone and the barrier height decreases. The voltage can be tapped at the diode. A current can only flow if the energy of the photons is higher than the energy of the band gap. As the energy is dependent on the wavelength of the photons, it also becomes clear why different materials have to be used for different wavelength ranges.
A photodiode is characterized by its dark current. This is the current that continues to flow even when it is dark. Although this current is very low, it is also temperature-dependent and must therefore not be ignored.

Features of our diodes:

  • Our highly sensitive silicon PIN photodiodes as a chip from 390 to 1500 nm cover a broad spectrum
