Laser scribing apparatus, systems, and methods |
摘要 |
Apparatus, systems, and methods for forming a photovoltaic cell from a common layer on a substrate are provided. A first pass is made with a first laser beam over an area on the common layer. The first pass forms a groove in the common layer. The first pass forms within the common layer a first edge and a second edge. The first edge is separated from the second edge by the groove. The groove provides a first level of electrical isolation between the first edge and the second edge. A second pass is made with a second laser beam over approximately the same area on the common layer. The second pass provides a second level of electrical isolation between the first edge and the second edge. The second level of electrical isolation is greater than the first level of electrical isolation.
