A reverse-biased voltage applied to a semiconductor with P and N regions and a PN-junction to create a wider depletion layer. When a quanta impinges upon the semiconductor the electrons are released to move toward the cathode and holes toward the anode (a) (adapted from [11]). The reverse current produced is proportional to light intensity (b). Photograph of photodiode (c)
