Photoconductivity refers to the characteristic of a material or substance that indicates the degree to which it conducts electricity under illumination, or light. This phenomenon is commonly observed in certain types of materials, including semiconductors and conductive polymers. Some synonyms for photoconductivity include photovoltaic, photoelectric, and photosensitivity. Photovoltaic refers to the generation of electrical current or voltage in a material or device in response to light, while photoelectric pertains to the absorption of light energy by an object and the consequent emission of electrons. Photosensitivity describes the ability of a material or substance to be affected by light, such as the sensitivity of light-sensitive chemicals to certain wavelengths of light.
