Quantum Efficiency ɳ:

  1. Quantum Efficiency is defined as the ratio of number of electrons collected to the number of incident photons.

  2. It is also defined as ratio of generated current flux to input photon flux.

$ɳ_q = \dfrac {\text {number ofelectrons collected}}{\text {number ofincident photons}} \\ ɳ_q = \dfrac {R_e}{R_p} …
