The invention relates to an apparatus for depositing thin film coatings on a substrate. The deposition apparatus is designed to keep gaseous reactant materials to be deposited apart from one another in the deposition apparatus, by one or more separation devices and/or methods, but nevertheless, to allow the chemical reactants to mix and react at or near the substrate surface, rapidly enough to create a uniform film at commercially viable deposition rates.

Process for forming a silica coating on a glass substrate

A process for coating a ribbon of float glass is disclosed. It comprises the steps of forming a glass ribbon, depositing a first transparent conductive coating upon a major surface of the ribbon which does not extend to the edges of the ribbon while the ribbon is at an elevated temperature, cooling said coated ribbon under controlled conditions in an annealing lehr and cutting off the edges of the ribbon so as to produce a ribbon having a uniform coating extending across the full width of the cut ribbon which is characterized in that a second conductive coating is deposited upon the uncoated edges of the ribbon while that edge is at a temperature which is above the ambient temperature. The invention finds particular application in the production of coated glass products where the thickness of the glass ribbon is at least 8 mm and most particularly where the thickness of the glass is at least 10 mm.

A method for removing oxygen from molten tin in the float bath chamber of a float glass manufacturing process is provided. The method includes providing a chamber having within it molten metal and a gaseous atmosphere above the molten metal, providing at least one reducing gas container proximate the interface between the molten metal and the gaseous atmosphere, providing a source of a reducing gas, and directing the reducing gas to the at least one container. In the at least one container, the reducing gas reacts with the oxygen in the molten metal. The method may include removing a vapor/particulate stream from the float bath chamber. The method may also include removing the vapor and/or the particulate from the stream. An apparatus for removing oxygen from the molten tin is also provided.

A multi-layer thin film stack, particularly suitable as a component of a solar cell, is deposited on a transparent dielectric substrate. The multi-layer film stack comprises a transparent electrically conductive metal oxide layer deposited over the dielectric substrate, the conductive metal oxide layer having a refractive index less than 2.0, a light transmittance optimizing interlayer having a refractive index between 2.3 and 3.5, deposited over the electrically conductive metal oxide layer, and a silicon layer having a refractive index of at least 4.5 deposited over the light transmittance optimizing interlayer. The film stack can be deposited by any suitable method, but deposition of each of these layers by atmospheric chemical vapor deposition is preferred.

Light transmittance optimizing coated glass article for solar cell and method for making

One or more coating precursors are selected from metal or silicon compounds at a temperature above their melting points but substantially below their standard vaporization temperature, thereby causing the coating precursors to be in the form of a liquid. A vaporization chamber has a structure for continually injecting the liquid coating precursor into the chamber to produce a vapor. A seal-less, magnetically driven portion rotates a structure for distributing the liquid coating precursor in the vaporization chamber. In one embodiment, a barrier gas is injected adjacent the chamber at a velocity greater than the diffusion velocity of the vapor to prevent the vapor from communicating with the magnetically driven portion. In another embodiment, a first portion of the magnetically driven portion is connected to a structure for distributing the liquid coating precursor in the vaporization chamber. The second portion, located adjacent the first portion, but outside the vaporization chamber, magnetically couples with and rotates the first portion.

The invention is a method of making a coated glass substrate having a low haze. A soda-lime glass substrate having at least one surface upon which a coating may be deposited is provided. The glass substrate is heated and maintained at a temperature sufficient to volatilize salts that may be formed during the depositing of a first coating on the glass substrate. A first gaseous precursor mixture including a halogen containing precursor, a metal precursor, an oxidizing agent, and an inert to carrier gas is directed toward and along the surface to be coated and reacting the mixture at or near the surface of the glass substrate to form a first coating containing a metal oxide coating. The glass substrate is cooled to a temperature to reduce crystalline growth in a second coating to be applied over the first coating. A second gaseous precursor mixture including a second metal precursor, an oxidizing agent, and an inert carrier gas is directed toward and along the coated surface of the glass substrate and reacting the mixture at or near the coated surface to form a metal containing coating. The glass substrate is cooled to an ambient temperature. The invention also includes a coated glass substrate produced in accordance with the aforementioned method.
