Relating to electrical properties that are produced or modified by exposure to radiation, or describing a material that becomes electrically active when exposed to light.
From actino- (Greek aktis, 'ray') + dielectric (from di-, 'through' + electric, from elektron, 'amber'). This term emerged in early 20th-century physics as scientists studied photoelectric effects.
Actinodielectric materials are the foundation of solar panels—when light hits certain semiconductors, it literally creates an electrical field that pushes electrons forward, converting sunlight directly into the electricity powering our devices.
