A method of preventing or reducing fogging of a surface of a composite when subjected to humid conditions includes providing a composite with a surface. The composite includes a substrate and a photocatalytic surface layer. The photocatalytic surface layer includes a photocatalyst. The method further includes subjecting the photocatalyst to photoexcitation to render the surface of the composite hydrophilic, wherein, after the photoexcitation, the surface of the composite has a water wettability of less than 10° in terms of the contact angle with water. The method further includes subjecting the composite to humidity that is sufficient to induce fogging of the substrate if the photocatalytic surface layer were absent.

An interlayer for laminated glasses which does not cause the moire phenomenon even when having an embossed pattern with grooves and ridges disposed regularly or arranged at a regular interval, hence has satisfactory workability in cutting or laminating, and is highly effective in expelling air in preliminary press bonding; and a high-quality laminated glass produced with the same which is almost free from quality defects caused by residual bubbles. The interlayer is highly effective in air expelling even without strictly controlling the air expelling initiation temperature in the preliminary press bonding, is excellent in nonblocking properties during storage, handleability during glass processing, and productivity, and can be easily and efficiently used under various processing conditions. It comprises a thermoplastic resin sheet having on each side thereof an embossed pattern comprising grooves and ridges.

This invention relates to a front electrode/contact for use in an electronic device such as a photovoltaic device. In certain example embodiments, the front electrode of a photovoltaic device or the like includes a multilayer coating including at least one transparent conductive oxide (TCO) layer (e.g., of or including a material such as tin oxide, ITO, zinc oxide, or the like) and/or at least one conductive substantially metallic IR reflecting layer (e.g., based on silver, gold, or the like). In certain example instances, the multilayer front electrode coating may include one or more conductive metal(s) oxide layer(s) and one or more conductive substantially metallic IR reflecting layer(s) in order to provide for reduced visible light reflection, increased conductivity, cheaper manufacturability, and/or increased infrared (IR) reflection capability.

A method of cleaning a semiconductor fabrication processing chamber involves recirculation of cleaning gas components. Consequently, input cleaning gas is utilized efficiently, and undesirable emissions are reduced. The method includes flowing a cleaning gas to an inlet of a processing chamber, and exposing surfaces of the processing chamber to the cleaning gas to clean the surfaces, thereby producing a reaction product. The method further includes removing an outlet gas including the reaction product from an outlet of the processing chamber, separating at least a portion of the reaction product from the outlet gas, and recirculating a portion of the outlet gas to the inlet of the processing chamber.
