Photodiode: Definition, applications, and more

The photoelectric effect and its role in solar photovoltaics . b. Photodiode history. The built-in electric field generates a potential difference in which the anode is positive with respect to the cathode. Simply put, the potential difference generates a forward voltage in the order of millivolts to volts.

Photodiode

Similarly, in the photodiode, there is a built-in-potential difference across the depletion region. When a light ray or photon of enough energy (hv) greater than the energy gap (Eg) falls on the junction of the photodiode, it dislodges or removes an electron from its valance band into the conduction band.
