It gained this energy from the incident electromagnetic wave. In the space between the electrodes, a photoelectron moves in the electric potential and its energy changes by the amount qΔV, where ΔV is the potential difference and q = − e.
WebThe difference between the both of them is that a solar cell produces power for electrical circuits, while a photocell is a control switch that is light-activated. Moreover, photocells have been used since the mid-1900s, while solar cells have only been used since 1990. However, both solar cells and photocells need light to work. WebIllumination frees electrons and holes on opposite sides of the junction to produce a voltage across the junction that can propel current, thereby converting light into electrical …
WebOne of the major difference between the photodiode and the phototransistor is that the photodiode uses PN-junction diode which converts the light energy into an electric current, whereas the phototransistor uses the ordinary transistor (NPN transistor) for the conversion of light into current.Some other differences between the photodiode and …
