    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 front electrode provided on an etched/patterned front glass substrate for use in a photovoltaic device or the like. The glass is a low-iron soda-lime-silica based glass. Etching of the glass may include immersing the soda-lime-silica based glass in an acid inclusive solution such as hydrofluoric acid (e.g., HF in aqueous solution) and/or hydrofluoric acid with a buffer, in order to selectively dissolve some of the glass thereby producing at least one textured/patterned substantially transparent surface of the glass substrate. A front electrode (single or multi-layered) is then formed (e.g., via sputter-deposition) on the textured surface of the front glass substrate, and may be used in a photovoltaic device or the like.

    摘要: Certain example embodiments relate to a sunlight-scattering thin-film coating disposed on a substrate for greenhouse applications. The surface morphology of the coating promotes a better and more uniform light distribution. For instance, at least one thin-film layer disposed on a substrate may be textured so as to create surface features on the order of 0.1-5 microns, with the surface features being sized to cause (a) light having a wavelength of greater than or equal to about 800 nm incident thereon to primarily scatter to angles less than 30 degrees relative to a major surface of the substrate and (b) light having a wavelength of less than or equal to about 700 nm incident thereon to primarily scatter to angles greater than 20 degrees relative to the major surface of the substrate. This arrangement may advantageously direct beneficial light towards plant life while directing parasitic light away from the plant life.

    摘要: A photovoltaic device includes a front electrode on a textured front glass substrate. In certain example embodiments, the glass substrate is textured via roller(s) and/or etching to form a textured surface. Thereafter, a front electrode is formed on the textured surface of the glass substrate via pyrolysis. The front electrode may be of or include a transparent conductive oxide (TCO) such as tin oxide and/or fluorinated tin oxide in certain example embodiments. In certain example instances, this is advantageous in that efficiency of the photovoltaic device can be improved by increasing light absorption by the active semiconductor via both increasing light intensity passing through the front glass substrate and front electrode, and increasing the light path in the semiconductor photovoltaic conversion layer.

    摘要: A photovoltaic device including a rear electrode which may also function as a rear reflector. In certain example embodiments of this invention, the rear electrode includes a metallic based reflective film that is oxidation graded, so as to be more oxided closer to a rear substrate (e.g., glass substrate) supporting the electrode than at a location further from the rear substrate. In other words, the rear electrode is oxidation graded so as to be less oxided closer to a semiconductor absorber of the photovoltaic device than at a location further from the semiconductor absorber in certain example embodiments. In certain example embodiments, the interior surface of the rear substrate may optionally be textured so that the rear electrode deposited thereon is also textured so as to provide desirable electrical and reflective characteristics. In certain example embodiments, the rear electrode may be of or include Mo and/or MoOx, and may be sputter-deposited using a combination of MoOx and Mo sputtering targets.
