Q. In a p − n junction photo cell, the value of the photo-electromotive force produced by monochromatic light is proportional to The barrier voltage at the p-n junction. The intensity of the light falling on the cell. The frequency of the light falling on the cell. The voltage applied at the p-n junction.
The photons in the light, when they strike the free electrons, transmit the energy to the free electron and it moves forward, this develops a current and electromotive force in the photocell. The value of this electromotive force is dependent on the photons from the light.
Hint: The PN P N junction photocell is also called a photodiode. The photodiode converts the photons into the current. This can also say that the photodiode produces current when the light falls on it. The electromotive force is similar to the potential difference across the two junctions. The electromotive force is developed inside the cell.
An electric photocell is a device whose electrical properties (voltage, resistance, …) vary according to the intensity of the light radiation captured. It is a photosensitive sensor. It is strongly recommended to use photocells that come with a transmitter and infrared receiver in mechanical sports.
Therefore electromotive force is also proportional to the intensity of the light falling on the photocell. The interface or the boundary between the two-semiconductor material is known as a PN P N junction. In the PN P N junction the excess holes are found near the p p junction that is known as the positive side.
