摘要:
In continuous apparatus for the glow discharge deposition of amorphous silicon alloy solar cells of p-i-n-type configuration in a plurality of interconnected, dedicated deposition chambers, a plasma bar operatively disposed between at least the plasma regions in which the layer pairs of amorphous silicon alloy material defining the major semiconductor junction of the solar cell are deposited. The plasma bar is adapted to initiate a plasma so as to prevent chemically adsorbed contaminants from deleteriously affecting the surface of the first deposited of the layer pair, thereby improving the open circuit voltage of the solar cell. In a similar manner, the plasma bar may also be provided between the layer pairs of amorphous silicon alloy material which combine to define the minor semiconductor junction of the solar cell. Finally, a plasma bar may be disposed between the oxide-based layer of a back reflector for reducing oxygen contamination of the silicon alloy material deposited thereupon.

An improved gas gate (34) is adapted to operatively interconnect to adjacent chambers in which process gases are introduced for depositing a first layer (16) upon a substrate (11) in a first chamber (28) and different process gases are introduced for depositing a second layer (18) in the second chamber (30) in continuous low pressure glow dicharge deposition process. A plurality of electrodes (60) and grounded shields (62) are positioned in the isolation passageway (92) of gas gate (34). The electrodes (60) have a potential sufficient to create a plasma from any gas molecule escaping from one of the deposition chambers. After the plasma is formed it is attracted to and captured or plated on the shield (62) preventing the gas plasma from landing on the substrate material (11) or passing through the gas gate. The present invention reduces the back diffusion of gases through the gas gate by actively eliminating free gas molecules by ionizing them to form a plasma and capturing the plasma ions in a permanent fashion.

A multilayered, light-scattering back reflector for a photovoltaic device, said back reflector including a first relatively hard, textured layer atop a substrate and a second highly reflective layer conformally disposed atop the first layer. The back reflector may further include a third light scattering layer formed atop said second layer, said third layer adapted to further provide a barrier layer between the body of semiconductor material from which the photovoltaic device is formed and the multilayered back reflector.
摘要:
A apparatus for depositing one or more thin film layers on one or more continuous web or discrete substrates. The apparatus includes a pay-out unit for dispensing one or a plurality of webs, a deposition unit that deposits a series of one or more thin film layers thereon, and a take-up unit that receives and stores the webs following deposition. In a preferred embodiment, deposition occurs through plasma enhanced chemical vapor deposition in which a plasma region is formed between a cathode in the deposition unit and one or more vertically-oriented webs. The instant deposition apparatus includes a support system for guiding and stabilizing the transport of one or more webs or substrates through the deposition chambers. The support system includes a magnetic guidance assembly and an edge-stabilizing assembly that operate to inhibit perturbations of the motion of a web or substrate in directions other than the direction of transport through the apparatus.

Methods and apparatus are provided for processing a print job including a plurality of raster image processed pages. A tab page is created that includes a tab image located at a predetermined position in the tab page, the predetermined position associated with a tab position on tab stock. The tab page is raster image processed, and the rasterized tab page is inserted at a selected position in the print job. The tab image is detected on the rasterized tab page at the predetermined location, and then the rasterized tab image is positioned at the associated tab position.

A photovoltaic roofing shingle includes a strip of roofing material having an overlap portion, and a plurality of tab portions depending therefrom. Each of the tab portions includes a photovoltaic generating device affixed thereto. The photovoltaic devices are electrically interconnected, and each photovoltaic shingle member includes a pair of electrical terminals for delivering power from said photovoltaic devices. In use, the shingle members are affixed to a roof so that the tab portions of one row of shingles cover the overlap portion of an adjoining row. Electrical interconnection may be made through the roof to the inside of the building, or to a point atop the roof.

The invention provides for automatic deployment, logging, and reporting of online course evaluations based on processing and access schedules and user access designations established by administrators at the time the evaluation survey is generated. Evaluation reports are automatically delayed until student final grades are submitted. Report notifications are sent via email to appropriate faculty and administration including a link or an encrypted link to access the reports.
摘要:
Method and apparatus for inserting tabs in a print job. A method for inserting tab sheets in a print job is disclosed. First, a position is selected within a document to insert a tab sheet, which document is comprised of a plurality of sheets each with a document defined image space associated therewith. A tab sheet is then created as a rasterized tab sheet image that has a rasterized tab specific image disposed in a predetermined location on the rasterized image. The created tab image is then inserted in the document after rasterizing thereof in the selected position.
