PHOTOCONDUCTION Meaning and
Definition
-
Photoconduction is a phenomenon found in certain materials that involves the alteration of electrical conductivity when exposed to light. It is the process by which the electrical conductivity of a material is modified under the influence of photons. When light energy is absorbed by the material, it promotes electrons from the valence band to the conduction band, thereby increasing the number of charge carriers and enhancing electrical conductivity.
In photoconductive materials, such as semiconductors, photons can excite electrons from the valence band to the conduction band, where they become free to move and contribute to electrical conduction. This process is responsible for the generation of photocurrent, which is an electric current that arises due to the absorption of light.
Photoconductive materials find various applications in devices like photodetectors, solar cells, and optoelectronic sensors. For instance, in a photodetector, the photoconductive material responds to light by becoming more conductive, allowing the detection and conversion of photons into electrical signals. Similarly, solar cells utilize photoconductive materials to convert incident light energy into electrical energy.
It is important to note that not all materials exhibit photoconduction. For a material to exhibit this behavior, it must possess a specific electronic structure and bandgap, enabling efficient light absorption and promotion of electrons to higher energy states.

Etymology of PHOTOCONDUCTION
The word "photoconduction" is derived from two main components: "photo" and "conduction".
-"Photo" comes from the Greek word "phos", meaning "light".
-"Conduction" comes from the Latin word "conducere", which means "to lead or bring together".
When combined, "photoconduction" refers to the process of conducting electricity or electrical charges through a material (conductor) using light. It is commonly used in the context of semiconductors acting as conductive pathways under the influence of light.
