Photoconductivity is a phenomenon in which the electrical conductivity of a material increases when it is exposed to light. This effect is primarily observed in semiconductor materials and certain insulators, where the absorption of photons generates additional charge carriers (electrons and holes), leading to enhanced electrical conductivity. Here's a more detailed breakdown of the process: 1. **Photon Absorption**: When light (photons) strikes a photoconductive material, its energy can be absorbed by electrons in the material.
