Abstract: An electrically conductive ceramic heating element for use in a reactor for depositing a film of material onto a semiconductor wafer, said reactor comprising a reactor chamber, a radiative heating device disposed within the reactor chamber including the heating element and operative for heating said wafer to a temperature of greater than 1100 degrees C., a wafer carrier disposed within the reactor chamber and adjacent to the radiative heating device, the wafer carrier having at least one wafer cavity for supporting a semiconductor wafer for having a film of material be deposited thereon.

Abstract: The terrestrial solar tracking photovoltaic array includes a longitudinal support that may be constructed of discrete sections. The overall length of the array may be adjusted depending upon the necessary size of the array. A drive may be configured to rotate the longitudinal support in first and second directions about a first axis. Solar cell modules are positioned along the longitudinal support and may each include a rectangular case with a plurality of lenses that are positioned over corresponding receivers. Linkages may be connected to the solar cell modules and are axially movable along the longitudinal support to rotate the solar cell modules within second planes that each orthogonal to the first plane to further track the sun during the course of the day. The array may be configured to facilitate rotation about the first axis. The array may be constructed with a center of gravity of the array to extending through the longitudinal support.

Abstract: Methods and devices for assembling a terrestrial solar tracking photovoltaic array. The methods may include securing a torque tube to an alignment fixture by positioning a flange at an end of the torque tube over a shelf on the alignment fixture and positioning a section of the torque tube inward from the flange into a receptacle on the shelf of the alignment fixture. The method may include aligning and mounting a mount to the torque tube at a point along the torque tube inward from the end of the torque tube. The method may include aligning and mounting a solar cell module to the mount with the solar cell module including an array of lenses positioned over a set of corresponding receivers that include one or more III-V compound semiconductor solar cells. The method may include removing the torque tube from the alignment fixture after the solar cell module is mounted to the mount.
