FAQ

What Is Photoelectric Cell In Physics?

A photoelectric cell is a device which is used to convert light energy into electrical energy. It is also called photocell or electric eye. There are three types of photoelectric cells: (1) Photo emissive cell. (2) Photo conductive cell.

What Is Called Photocell?

A photocell is a resistor that changes resistance depending on the amount of light incident on it. A photocell operates on semiconductor photoconductivity: the energy of photons hitting the semiconductor frees electrons to flow, decreasing the resistance.

How Is A Photoelectric Cell Made?

A photoelectric cell, also known as a photo-diode, can be made by creating a junction between a p-type semiconductor and an n-type semiconductor. This junction, called a p-n junction, allows for the flow of electrons when exposed to light.

What Is Photoemissive Cell?

A photo-emissive cell is a type of gas-filled or vaccum tube that is sensitive to light. It makes use of photo electric effects, the phenomenon whereby light sensitive surface give off electrons when stuck by light. when photons strike the cathod the electrons in the ligh-sensitive substance absorb the energy.
