摘要： A Schottky barrier amorphous silicon solar cell incorporating a thin highly doped p-type region of hydrogenated amorphous silicon disposed between a Schottky barrier high work function metal and the intrinsic region of hydrogenated amorphous silicon wherein said high work function metal and said thin highly doped p-type region forms a surface barrier junction with the intrinsic amorphous silicon layer. The thickness and concentration of p-type dopants in said p-type region are selected so that said p-type region is fully ionized by the Schottky barrier high work function metal. The thin highly doped p-type region has been found to increase the open circuit voltage and current of the photovoltaic device.

摘要： The present invention relates to an article and method for identification, classification, and inventory tracking of articles in bulk. The article has a first state and a second state. The state is the condition of the article including such states as new, used, broken, or depleted. When the article is new, it will have a perception indicating its state. The perception will be different from other perceptions of the article because of an identifiable characteristic which differentiates it from articles being in other states. The article has a second perception that is representative of a second state of the article. The second perception may be fixed upon or within the article or, in the alternative, the first perception may be such that, when the article changes state, the first perception changes into the second perception. The method of the invention comprises providing at least one article having at least a first state and a second state and providing each article with a first perception indicating the first state and a second perception indicating the second state of the article.

摘要： A loudspeaker with a pair of speaker units and a manifold chamber between the speaker units for combining the sound from both speaker units. The manifold chamber is formed by walls having an exit opening and a pair of rectangular apertures, the apertures confronting each other on opposite sides of the chamber and the exit opening being disposed normal to a plane centrally between the apertures, and the apertures and exit opening having parallel axes of elongation. One of the speaker units is coupled to each of the apertures to direct sound into the manifold chamber, and the manifold chamber is provided with a wedge confronting the apertures to direct sound parallel to the central plane between the apertures toward the exit opening. In one construction, a horn is coupled to the exit opening to conduct sound from the manifold chamber. Also in that construction, each of the speaker units has a vibratile cone confronting the apertures to which it is coupled and the cone is disposed in an enclosure provided with a bass reflex port.In another construction, four speaker units with vibratile cones are coupled to four apertures in walls forming a single manifold chamber with a single exit opening.In still another construction, a compression driver is coupled to each of the apertures through a transition section of the driver.

摘要： A photovoltaic device has a body which includes a thin film active region and a layer substantially transparent to solar radiation. The thickness of the transparent layer is such that a first antireflection condition is present for solar radiation at a wavelength which is relatively highly absorbed by the material of the active region. Furthermore, the combined thickness of the transparent layer and active region are such that a second antireflection condition is present for solar radiation at a wavelength which is poorly absorbed by the material of the active region. As a result of the prevailing antireflection conditions the solar radiation absorption efficiency of the photovoltaic device is increased.

摘要： A laser processing system can be utilized to produce high-performance interdigitated back contact (IBC) solar cells. The laser processing system can be utilized to ablate, transfer material, and/or laser-dope or laser fire contacts. Laser ablation can be utilized to remove and pattern openings in a passivated or emitter layer. Laser transferring may then be utilized to transfer dopant and/or contact materials to the patterned openings, thereby forming an interdigitated finger pattern. The laser processing system may also be utilized to plate a conductive material on top of the transferred dopant or contact materials.
