摘要: A solar cell fabrication procedure is described in which a trench is cut in the substrate so as to electrically isolate front and back regions of a flat solar cell. The trench is preferably cut around the perimeter of the rear side of the cell. The trench is preferably formed by an excimer laser which may be used to ablate a trench without diffusing conductive material deeper into the cell.

摘要: A solar cell fabrication procedure is described in which an excimer laser is used to cut a trench in a flat solar cell substrate so as to electrically isolate front and back regions of the substrate. The trench is cut around the perimeter of the cell. The advantage of using an excimer laser is that it will ablate a trench without diffusing conductive material deeper into the cell.
