    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. The front electrode has a transparent conductive oxide (TCO) film having first and second layers (continuous or discontinuous) of the same material (e.g., zinc oxide, zinc aluminum oxide, indium-tin-oxide, or tin oxide), where the first TCO layer is sputter-deposited using a ceramic sputtering target(s) and the second TCO layer of the same material is sputter-deposited using a metallic or substantially metallic sputtering target(s). This allows the better quality TCO of the film, deposited more slowly via the ceramic target(s), to be formed using the ceramic target and the lesser quality TCO of the film to be deposited more quickly and cost effectively via the metallic target(s). After the etching, most or all of the better quality ceramic-deposited TCO remains whereas much of the lesser quality metallic-deposited TCO of the film was removed during the etching process.

    摘要: Certain example embodiments of this invention relate to a high transmission low iron glass, which is highly oxidized and made using the float process, for use in photovoltaic devices such as solar cells or the like. In certain example embodiments, the glass composition used for the glass is made via the float process using an extremely high and positive batch redox in order to reduce %FeO to a low level and permit the glass to consistently realize a combination of high visible transmission (Lta or T vis ), high infrared (IR) transmission, and high total solar (TS) transmission. The glass substrate may be patterned or not patterned in different example embodiments of this invention.

    摘要: A coated article is provided with a low-emissivity (low-E) layer stack for use in a window unit or the like. The layer stack, or coating, may permit the coated article to achieve one or more of a low solar factor (SF) value, a high selectivity (T vis /SF) value, substantially neutral color at normal and/off-axis viewing angles, and/or low emissivity. When high selectivity values are achieved, there is provided a high ratio of visible transmission to SF, which is a desirable feature in certain example instances. In certain example embodiments , a sub-oxide layer (e.g., NiCrO x ) may be used as a contact layer under an infrared (IR) reflecting layer in order to permit low SF values, high selectivity , and good coloration to be achieved.
