SOLAR CELL CONTACT FORMATION PROCESS USING A PATTERNED ETCHANT MATERIAL |
摘要 |
Embodiments of the invention contemplate the formation of a high efficiency solar cell using novel methods to form the active region(s) and the metal contact structure of a solar cell device. In one embodiment, the methods include the use of various etching and patterning processes that are used to define point contacts through a blanket dielectric layer covering a surface of a solar cell substrate. The method generally includes depositing an etchant material that enables formation of a desired pattern in a dielectric layer through which electrical contacts to the solar cell device can be formed.
