AI Customer ServicePhotoelectric 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).
Photocells is an umbrella term for different types of photoelectric cells which mainly use the light energy or radiation emitted by the sun, absorb it and convert it into electrical energy.
There are, essentially, three types of photoelectric cell; the photoemissive cell, the photovoltaic cell, and the photoconductive cell. The first of these depends on the fact that certain surfaces, notably those composed of the alkali metals and their oxides, e.g. caesium, potassium, etc., emit electrons when light falls upon them.
They write new content and verify and edit content received from contributors. photoelectric cell, an electron tube with a photosensitive cathode that emits electrons when illuminated and an anode for collecting the emitted electrons.
The photoelectric effect has three important characteristics that cannot be explained by classical physics: (1) the absence of a lag time, (2) the independence of the kinetic energy of photoelectrons on the intensity of incident radiation, and (3) the presence of a cut-off frequency. Let’s examine each of these characteristics.
The photoelectric effect is determined by a variety of parameters, comprising light frequency, intensity, material type, light energy, and potential difference. Electron emission is not affected by light intensity unless the frequency exceeds a certain threshold.
