WebJul 11, 2024 · Photoconductors. The operating principle of the photoconductors is based on photoconductive effect, that is, the conductivity of the materials changes under illumination. The photoconductors without p-n junction always need an external electric field to separate the photogenerated carriers from electron-hole pairs. WebJan 11, 2024 · The photodiode. The photodiode is a two-element P-N or PIN junction that is exposed to light through a transparent body or cover. When light strikes the junction, a current or voltage is developed depending on the mode of operation. The photodiode operates in any of three modes depending on the biasing applied to it.
