quantum efficiency (of a photosensitive device)
The ratio of the number of effective electron-hole pairs produced within the device to the number of incident photons.
NOTE For devices that internally amplify or multiply the electron‑hole pairs (such as phototransistors or avalanche photodiodes), the effect of the gain is to be excluded from quantum efficiency.
