The organic photographic sensor

This new generation sensor uses a more light-sensitive organic layer than conventional photodiode based sensors.


  • More sensitive than ccd / cmos sensors to natural light
  • Cheaper than silicon sensors
  • More efficient than micro-lenses
  • Less sensitive than conventional infrared sensors
  • Less energy consuming than capacitive sensors


The digital technology of CCD and CMOS sensors limits their dynamics and sensitivity. On a BSI CMOS sensor, each photosite is composed of a photodiode and a read circuit. The problem lies in the fact that the diode is necessarily smaller than the photosite since it is isolated from neighbouring diodes: some photons arrive between the diodes and therefore do not reach the sensitive surface. To concentrate as many photons as possible on the diodes, extremely complex micro-lens arrays are used to install on the sensor. But the result is that a significant part of the light is lost.


Replace the silicon photodiode layer of the sensors with a layer of a photosensitive organic compound with a spectral sensitivity close to that of the eye. Instead of silicon photodiodes, it is a layer of an organic carbon-based compound, which produces an electrical charge when a photon touches it. The photoreceptor layer being uniform, photons can no longer fall between two photodiodes and be lost, so this type of sensor is more efficient.
