Description
Photovoltaic detectors (photodiodes) are semiconductor structures with one (PV) or multiple (PVM) , homo- or heterojunctions. Absorbed photons produce charge carriers that are collected at the contacts, resulting in external photocurrent. Photodiodes have complex current voltage characteristics. The devices can operate either at flicker-free zero bias or with reverse voltage. Reverse bias voltage is frequently applied to increase responsivity, differential resistance, reduce the shot noise, improve high frequency performance and increase the dynamic range.
