  "id": "MLC-T-ENV-004421",
  "term": "Cell Barrier",
  "field": "Environment",
  "definition": "Very thin region of static electric charge along the interface of the positive and negative layers in a photovoltaic cell. The barrier inhibits the movement of electrons from one layer to the other, so that higher-energy electrons from one side diffuse preferentially through it in one direction, creating a current and thus a voltage across the cell. Also called depletion zone or space charge. .",
