Abstract: A solar cell assembly for space application comprising a plurality of space-qualified solar cells and a support, the support comprising a conductive layer. The conductive layer is divided into a first conductive portion and a second conductive portion. Each space-qualified solar cell of the plurality of space-qualified solar cells comprising a front surface, a rear surface, and a first contact in correspondence with the rear surface. Each one of the plurality of space-qualified solar cells is placed on the first conductive portion with the first contact electrically connected to the first conductive portion so that the space-qualified solar cells are connected in parallel through the first conductive portion. A second contact of each space-qualified solar cell can be connected to the second conductive portion. The two conductive portions serve as bus bars of the space-qualified solar cell assembly.

Abstract: The present disclosure provides a multijunction solar cell comprising: an upper solar subcell having an indirect band gap semiconductor emitter layer composed of greater than 0.7 but less than 1.0 mole fraction aluminum and a base layer, the emitter layer and the base layer forming a heterojunction solar subcell; and a lower solar subcell disposed beneath the upper solar subcell, wherein the lower solar subcell has an emitter layer and a base layer forming a photoelectric junction. In some embodiments, the emitter layer of the upper solar subcell is an n-type AlxGa1-xAs layer with 0.7<x<1.0 and having a band gap of greater than 1.85 eV.

Abstract: A refrigerated merchandiser including a case defining a product display area and including a frame having a mullion. The mullion defining an opening to the product display area. A door is coupled and movable relative to the frame over the opening to provide access to the product display area. A refrigeration system is in communication with the product display area to condition the product display area. A first heater is coupled to and routed along the frame and a second heater is coupled to and routed along the frame. The second heater is separate from the first heater. A controller is operatively coupled to the first heater and the second heater and programmed to dependently control the first heater and the second heater relative to each other to remove or inhibit formation of condensation.

Abstract: The present disclosure provides methods of fabricating a multijunction solar cell panel in which one or more of the steps are performed using an automated process. In some embodiments, the automated process uses machine vision.

Abstract: A solar assembly or module comprising a plurality of solar cells and a support, the support comprising a conductive layer or back plane on each planar side. Each one of the plurality of solar cells is placed on the first conductive portion with the first contact electrically connected to the first conductive portion so that the solar cells are connected in parallel through the first conductive portion. A second contact of each solar cell can be connected to the second conductive portion so that the first and second conductive portions form terminals of opposite conductivity type. The modules can be interconnected to form a string or an electrical series connection of discrete modules by overlapping and bonding the first terminal of a first module with the second terminal of a second module.
