photoconductivity

the increase in the electrical conductivity of semiconductors and insulators when they are exposed to light of sufficient energy. Photoconductivity serves as a tool to understand the internal processes in these materials, and it is also widely used to detect the presence of light and measure its intensity in light-sensitive devices.
