    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: 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.
