  "id": "MLC-T-CHM-001894",
  "term": "Charge carrier injection",
  "field": "Chemistry",
  "definition": "The process of introducing mobile charge carriers, such as electrons or holes, from an external electrode into a polymeric material. This is a fundamental step in the operation of many organic electronic devices, including organic light-emitting diodes and organic solar cells. The efficiency of injection depends on the energy level alignment between the electrode and the polymer.",
