Spectrolab 12-045774-301 8.5in GaAs Solar Cell Wafer Container 25 Holders Space

Spectrolab 12-045774-301 8.5in GaAs Solar Cell Wafer Container 25 Holders Space

The Spectrolab 12-045774-301 is an 8.5-inch solar cell wafer container designed to safely store and transport GaAs (gallium arsenide) photovoltaic wafers in a semiconductor or photovoltaic manufacturing environment. Manufactured by Spectrolab — a Boeing subsidiary and leading producer of high-efficiency space solar cells — this container holds 25 individual wafer holders within a rigid, clear polypropylene housing fitted with a blue circular carrier tray. The label affixed to this unit identifies it as Batch TAC900022A, packaging date 11/20/2009, with 25 wafers and 1,580 noted good cells at the time of original packaging.

Applications

Spectrolab GaAs solar cell wafer containers are used in the handling, transport, and storage of III-V compound semiconductor wafers — primarily gallium arsenide (GaAs) photovoltaic cells produced for space and high-efficiency solar applications. Spectrolab, headquartered in Sylmar, California, has long been a primary supplier of solar arrays for NASA satellites, the International Space Station, and commercial geostationary spacecraft. Their GaAs multi-junction solar cells are used where maximum efficiency in a minimum footprint is critical — spacecraft, high-altitude UAVs, and concentrated photovoltaic (CPV) systems. Wafer containers like this one maintain wafer integrity during inter-facility transfer and storage within a cleanroom or fab environment, protecting fragile GaAs cells from contamination and breakage. These containers are also sought by researchers, universities, and solar energy labs working with GaAs photovoltaic substrates or studying high-efficiency PV cell fabrication.
