摘要:
Certain example embodiments of this invention relate to photovoltaic modules that include high contact angle coatings on one or more outermost major surfaces thereof, and/or associated methods. In certain example embodiments, the high contact angle coatings advantageously reduce the likelihood of electrical losses through parasitic leakage of the electrical current caused by moisture on surfaces of the photovoltaic modules, thereby potentially improving the efficiency of the photovoltaic devices. In certain example embodiments, the high contact angle coatings may be nitrides and/or oxides of or including Si, Ti, Ta, TaCr, NiCr, and/or Cr; hydrophobic DLC; and/or polymer-based coatings. The photovoltaic modules may be substrate-type modules or superstrate-type modules in different example embodiments.

Certain example embodiments of this invention relate to techniques for reducing stress asymmetry in sputtered polycrystalline films. In certain example embodiments, sputtering apparatuses that include one or more substantially vertical, non-conductive shield(s) are provided, with such shield(s) helping to reduce the oblique component of sputter material flux, thereby promoting the growth of more symmetrical crystallites. In certain example embodiments, the difference between the travel direction tensile stress and the cross-coater tensile stress of the sputtered film preferably is less than about 15%, more preferably less than about 10%, and still more preferably less than about 5%.

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.

A transparent electrode is provided for an organic light emitting diode (OLED) device. The electrode may be made according to a method including: sputter-depositing a first layer of or including indium tin oxide (ITO) on a substrate; sputter-depositing a thin second metallic or substantially metallic layer on the glass substrate over the first layer to form an electrode structure, and heat treating the electrode structure at temperature(s) of at least about 400 degrees C. in order to thermally activate at least the first layer of or including ITO. The electrode structure may then be provided in an OLED device on the light-emitting side of the organic light emitting semiconductor layer.
摘要:
A transparent electrode is provided for an organic light emitting diode (OLED) device. In certain embodiments, the electrode is made by sputter-depositing first and second transparent conductive oxide (TCO) layers of the same material (e.g., ITO), but with different stoichiometries, on a substrate. The first TCO layer is more oxided than is the second TCO layer. The TCO layers of the electrode on the substrate may then be heat treated (HT) at high temperature(s) in order to increase the work function (WF) and/or increase visible transmission of the electrode. The electrode is provided in an OLED device.

摘要:
A method of making a coated article including a transparent conductive oxide (TCO) film supported by a tempered glass substrate is provided. Initially, an amorphous metal oxide film is sputter-deposited onto a non-tempered glass substrate, either directly or indirectly. The glass substrate with the amorphous film thereon is then thermally tempered using high temperatures. The thermal tempering causes the amorphous film to be transformed into a crystalline transparent conductive oxide (TCO) film. The heat used in the thermal tempering of the glass substrate causes the amorphous film to turn into a crystalline film, causes the visible transmission of the film to increase, and/or causes the film to become electrically conductive.
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 completing manufacture of the PV device, the etched surface of the front electrode faces the active semiconductor film of the PV device.
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:
There is provided a method of making a heat treated (HT) coated article to be used in shower door applications, window applications, or any other suitable applications where transparent coated articles are desired. The method may include heat treating a glass substrate coated with at least a layer of or including diamond-like carbon (DLC) or other type of carbon, with a protective film thereon. In certain example embodiments, the protective film may be of or include a layer of or including SnOx prior to HT. Optionally, a release layer of a material such as zinc oxide may be provided between the SnOx and the DLC. Following and/or during heat treatment the SnOx transforms into SnOy (y>x) so that stress is created due to the SnOx to SnOy transition. Then, during quenching, stress relief may occur which causes the layer to buckle, creating cracks which may act as liquid channels that permit the sacrificial film to be easily removed via washing or the like.
