Abstract: A glass substrate may be processed at high temperatures without substantially losing its thermal-strengthening characteristics or deforming. In some examples, the glass substrate exhibits an increased annealing point and/or softening point as compared to standard glass substrates. In some examples, the glass substrate includes a relatively high amount of CaO and/or MgO, and/or a relatively low amount of Na2O, as compared to traditional soda-lime-silica-based glass. Depending on the composition, the glass substrate may be useful, for example, to fabricate a glass-based solar cell that mates two substantially flat glass substrates together.

Abstract: A method of manufacturing monolithic glass reflectors for concentrating sunlight in a solar energy system is disclosed. The method of manufacturing allows large monolithic glass reflectors to be made from float glass in order to realize significant cost savings on the total system cost for a solar energy system. The method of manufacture includes steps of heating a sheet of float glass positioned over a concave mold until the sheet of glass sags and stretches to conform to the shape of the mold. The edges of the dish-shaped glass are rolled for structural stiffening around the periphery. The dish-shaped glass is then silvered to create a dish-shaped mirror that reflects solar radiation to a focus. The surface of the mold that contacts the float glass preferably has a grooved surface profile comprising a plurality of cusps and concave valleys. This grooved profile minimizes the contact area and marring of the specular glass surface, reduces parasitic heat transfer into the mold and increases mold lifetime.

Abstract: A fused glass crucible includes a collar of doped aluminum silica that defines uppermost and outermost surfaces of the crucible. The melt line that defines the surface of molten silicon in the crucible may be substantially at the lower end of the collar or slightly above it. Crystallization of the collar makes it hard and therefore supports the remaining uncrystallized portion of the crucible above the melt line. The melt line may also be below the lower end of the collar, especially if the melt is drawn down or poured early in the process. Because there is little or no overlap or because the overlap does not last long, the doped aluminum collar is not damaged by the heat of from the melt.

An air bearing may centripetally blow air against the expanding pre-form to limit expansion and prevent contact of the pre-form with the localized heat source. Meanwhile, the pre-form is pulled vertically to draw the heated glass. The pre-form may float in a floatation mechanism to compensate for gravity when the pre-form is pulled upward. The blown and drawn pre-form may be cooled, coated with a polymer layer, and cut into a ribbon by in-line devices as it exits the air bearing.
