Appl. No.:

10/368835

Inventors:

Joachim Doehler - Santa Barbara CA, US
Vincent Cannella - Beverly Hills MI, US

Assignee:

Energy Conversion Devices, Inc. - Rochester Hills MI

International Classification:

C23C016/00
C23C014/00
C23F001/00

US Classification:

118718, 15634531, 20429824, 118719, 118733

Abstract:

Disclosed herein is an improved gas gate for interconnecting regions of differing gaseous composition and/or pressure, more particularly between atmosphere and a vacuum. The gas gate includes a cylinder within a housing situated between the regions of differing gaseous pressure, wherein the gas gate provides for choke mode transonic flow of air leaks between the regions. A web of substrate material is adapted to move between the regions with at least one roller in a first region and at least one roller in a second region. The rollers are positioned to create sufficient tension as the web advances over the top peripheral portion of the cylinder between the two regions or under the bottom peripheral portion of the cylinder between the two regions.

International Classification:

H01Q003/22

US Classification:

342368000, 342375000, 3437000MS

Abstract:

A substrate is provided with a multiplicity of electrically conductive elements, and the elements are interconnected to form an antenna structure for desired application. Either the antenna pattern itself may be altered according to the invention, or one or more feed points may be changed, or all of the above. As such, the electrically conductive elements may be interconnected to change the directionality of the antenna pattern, the gain, the frequency response, or other operational characteristics. The electrically conductive elements may be arranged in the form of an inchoate antenna pattern or regular array. Switches at key points of the structure enable the pattern to be changed dynamically. Such switching may be carried out in real time in accordance with transmissions/reception characteristics, or in advance using simulations associated with the switched elements.

US Classification:

205 50, 205 91, 2042302

Abstract:

A metal and oxygen material such as a transparent electrically conductive oxide material is electro deposited onto a substrate in a solution deposition process. Process parameters are controlled so as to result in the deposition of a high quality layer of material which is suitable for use in a back reflector structure of a high efficiency photovoltaic device. The deposition may be carried out in conjunction with a masking member which operates to restrict the deposition of the metal and oxygen material to specific portions of the substrate. In particular instances the deposition may be implemented in a continuous, roll-to-roll process. Further disclosed are semiconductor devices and components of semiconductor devices made by the present process, as well as apparatus for carrying out the process.

Assignee:

United Solar Ovonic LLC - Auburn Hills MI

International Classification:

C23C 16/04
B05D 5/06
B05C 13/00

US Classification:

427 66, 118500, 118 33, 118718

Abstract:

A continuous roll-to-roll apparatus for providing a patterned deposit of a material onto a moving substrate web includes a payout station for feeding out a substrate web, a take-up station for taking up the substrate web, and a web transport system for advancing the web through the apparatus from the payout station to the take-up station. The apparatus includes at least one deposition station disposed between the payout station and the take-up station, and the deposition station is operative to deposit a material onto the web as it moves therethrough. The apparatus includes a masking system associated with a deposition station. The masking system is operative to dispose a deposition mask in registry with a portion of the length of the moving web. The deposition mask is comprised of a plurality of filaments which are aligned with the longitudinal axis of the web. The filaments are spaced from one another in a direction transverse to the longitudinal axis, and the masking system is further operative to move the filaments along the longitudinal axis, and the filaments function to selectively mask longitudinal portions of the moving web so as to prevent the deposition of material thereupon. Also disclosed are methods for utilizing the system.

Appl. No.:

6/240493

Inventors:

Masatsugu Izu - Birmingham MI
Vincent D. Cannella - Detroit MI
Stanford R. Ovshinsky - Bloomfield Hills MI

Assignee:

Energy Conversion Devices, Inc. - Troy MI

International Classification:

H01L 3104

US Classification:

427 39

Abstract:

The continuous production of solar cells by the glow discharge (plasma) deposition of layers of varying electrical characteristics is achieved by advancing a substrate through a succession of deposition chambers. Each of the chambers is dedicated to a specific material type deposition. The chambers are mutually isolated to avoid the undesired admixture of reaction gases therebetween. Each plasma deposition is carried out in its glow discharge area, chamber, or chambers, with isolation between the plasma regions dedicated to different material types. Masking, mechanical or lithographic, can be employed relative to the substrate to cause the deposition in the desired configuration. After the semiconductor deposition is complete, top contact and anti-reflection layer or layers are deposited, followed by a protective lamination.
