Method for forming structures in a solar cell
A conductive contact pattern is formed on a surface of solar cell by forming a thin conductive layer over at least one lower layer of the solar cell, and ablating a majority of the thin conductive layer using a laser beam, thereby leaving behind the conductive contact pattern. The laser has a top-ha...

| Zusammenfassung: | A conductive contact pattern is formed on a surface of solar cell by forming a thin conductive layer over at least one lower layer of the solar cell, and ablating a majority of the thin conductive layer using a laser beam, thereby leaving behind the conductive contact pattern. The laser has a top-hat profile, enabling precision while scanning and ablating the thin layer across the surface. Heterocontact patterns are also similarly formed. |
