摘要:
Certain example embodiments of this invention relate to a photovoltaic (PV) device including an electrode such as a front electrode/contact, and a method of making the same. In certain example embodiments, the front electrode has a textured (e.g., etched) surface that faces the photovoltaic semiconductor film of the PV device. In certain example embodiments, the front electrode is formed on a flat or substantially flat (non-textured) surface of a glass substrate (e.g., via sputtering), and the surface of the front electrode is textured (e.g., via etching). In certain example embodiments, a combination of two or more different etchants can be used in order to provide the front electrode with a textured surface having at least two different feature sizes. In completing manufacture of the PV device, the etched surface of the front electrode faces the active semiconductor film of the PV device.
