A photodiode has quantum efficiency of 45% and incident photons are 3*1011. Determine electrons collected at terminals of device. Correct Answer 1.35*1011

Quantum efficiency is given by Quantum efficiency = No. of electrons collected/No. of incident photons Electrons collected = Quantum efficiency * number of incident photons = 45/100 * 3*1011 = 1.35*1011.
