Abstract:
A method and apparatus for forming semiconductor particles (42) for solar cells using an optical furnace (30). Uniform mass piles (26) of powered semiconductor feedstock are almost instantaneously optically fused to define high purity semiconductor particles without oxidation. The high intensity optical energy is directed and focused to the semiconductor feedstock piles (26) advanced by a conveyer medium (16) thereunder. The semiconductor feedstock piles (26) are at least partially melted and fused to form a single semiconductor particle (42) which can be later separated from a refractory layer (18) by a separator (50), preferably comprised of silica. The apparatus (10) and process is automated, providing a high throughput to produce uniform mass, high quality spheres for realizing high efficiency solar cells. The apparatus is energy efficient, whereby process parameters can be easily and quickly established.

Abstract:
In one embodiment of the present invention as used for impregnating a composite tape (56) with HTC particles provides for permeating a fabric layer (51) of the composite tape with HTC particles and impregnating an impregnating resin into the composite tape through the fabric layer (51). At least 5% of the HTC particles permeated into the fabric layer are carried out of the fabric layer and into a mica layer (52) bound to the fabric layer by the impregnating resin. In some embodiments the impregnating resin itself contains HTC particles.

Abstract:
In one embodiment the present invention improves the heat flow from an electrically insulated object 13 by providing an enhanced conduit at the interface between the layers of insulating tape 16. The tape 16 has been surface coated with a high thermal conductivity (HTC) material, so that the interface between the layers of tape 23 provides a pathway for the heat to reach the environment 24. The radiation of heat through the tape layers is also increased by the surface coatings

Abstract:
The disclosure provides a process for producing a material with improved breakdown strength. The process includes heating a polymeric composition composed of a low density polyethylene (LDPE) and a minority amount of a high density polyethylene (HDPE). The polymeric composition is heated to at least the melting temperature of the HDPE. The process includes control-cooling the heated polymeric composition at a cooling rate from 0.1 °C/min to 20°C/min, and forming a polymeric composition. The control-cooled polymeric composition has a unique morphology which improves breakdown strength. Also provided is a coated conductor with an insulating layer composed of the polymeric composition with the unique morphology. The insulating layer exhibits improved breakdown strength.
