摘要:
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.

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.

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 of producing front surface mirrors comprising depositing onto a hot ribbon of low transmissivity glass during the production process a low transmissivity reflecting coating whereby the mirrors have a transmissivity through the coated glass of up to about 10% in visible light. There is also provided a front surface mirror comprising a glass substrate of low transmissivity glass carrying a low transmissivity reflecting coating whereby the mirror has a transmissivity through the coated glass of up to about 10% in visible light.
摘要:
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.
