    • 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.
    • 本发明的某些示例性实施例涉及包括诸如前电极/触点的电极的光伏(PV)装置及其制造方法。 在某些示例性实施例中,前电极具有面向PV器件的光电半导体膜的有纹理(例如蚀刻)的表面。 在某些示例性实施例中,前电极形成在玻璃基板(例如,通过溅射)的平坦或基本上平坦的(非纹理的)表面上,并且前电极的表面是有纹理的(例如通过蚀刻)。 在某些示例性实施例中,可以使用两种或更多种不同蚀刻剂的组合,以便为前电极提供具有至少两种不同特征尺寸的纹理表面。 在完成PV器件的制造中,前电极的蚀刻表面面对PV器件的有源半导体膜。
