Photoconductive mode
WebA photodetector salvaged from a CD-ROM drive. The photodetector contains three photodiodes, visible in the photo (in center). Photodetectors, also called photosensors, are sensors of light or other electromagnetic … WebPhotodiodes can be used under either zero bias (photovoltaic mode) or reverse bias (photoconductive mode). In zero bias, light falling on the diode causes a current across the device, leading to forward bias which in turn induces "dark current" in the opposite direction to the photocurrent. This is called the photovoltaic effect, and is the ...
