Since photocell work on the emission of electrons with light incident on it, the working principle of a photocell is the photoelectric effect. Stay updated with the Physics questions & answers with Testbook. Know more about Dual Nature: Photon and Matter Waves and ace the concept of Experimental Study of Photoelectric Effect.
Describe the construction of photoelectric cell. A photoelectric cell is device which converts light energy into electrical energy. It works on the principle of photoelectric effect. Construction : A photoelectric cell consist a small evacuated bulb. A thin layer of an alkali metal is deposited on inner surface of the bulb.
A " photoelectrochemical cell " is one of two distinct classes of device. The first produces electrical energy similarly to a dye-sensitized photovoltaic cell, which meets the standard definition of a photovoltaic cell.
Photoelectric cell or photocell or photovoltaic cell is an electronic device which works on the principle of the photoelectric effect and converts light energy into electrical energy. Construction: Photocell consists of an evacuated glass tube containing two electrodes emitter (C) and Collector (A).
The photoelectric cell is used in exposure meter. The exposure meter is used along with a camera to know the correct time of exposure for having a good photograph. The photoelectric cell is used in lux-meter. It is used to determine the intensity of light. The photoelectric cell is used in a burglar alarm.
A photocell is a resistor that changes resistance depending on the amount of light incident on it. You might find these chapters and articles relevant to this topic. Ian Sinclair, in Passive Components for Circuit Design, 2001 A photocell is a light-to-electrical transducer, and there are many different types available.
A "photoelectrochemical cell" is one of two distinct classes of device. The first produces electrical energy similarly to a dye-sensitized photovoltaic cell, which meets the standard definition of a photovoltaic cell. The second is a photoelectrolytic cell, that is, a device which uses light incident on a photosensitizer, semiconductor, or aqueous metal immersed in an electrolytic solution to directly cause a chemical reaction, for example to produce hydrogen via the electrolysis of water.
