Free charge-carrier photogeneration

{
  "id": "MLC-T-CHM-004649",
  "term": "Free charge-carrier photogeneration",
  "field": "Chemistry",
  "definition": "The process by which incident light energy creates mobile charge carriers, such as electrons and holes, within a material. This occurs when photons are absorbed, exciting electrons to higher energy states where they can move freely through the material's lattice. The efficiency of this process is a key parameter in photovoltaic devices.",
