AZUR SPACE Solar Power

AZUR SPACE Solar Power is a maker of solar cells for satellites. It is based in Heilbronn, Germany, and has worked from the same place since it was founded in 1964. The company says it is a major supplier of space solar cells. Since 2022 it has been owned by 5N Plus Inc. of Montreal, Canada.

The company makes multi-junction solar cells. They are used in space power systems and in terrestrial concentrating photovoltaic systems. Its products include cells and coverglass interconnected cell assemblies. The site lists a first quadruple junction space solar cell and a triple junction cell with record efficiency, made with Fraunhofer ISE. The same technology is used in photovoltaic systems and in opto and power electronic devices.

The history page says the first products flew on Germany's first satellite, Azur, in 1969. The company has been part of AEG, Telefunken, Daimler Chrysler Aerospace, ASE, RWE and Generali before joining 5N Plus. In 2007 it took its current name. It says it has delivered more than 16 million solar devices, including over 6 million multi-junction units, to more than 2,500 space projects. It reports no failure or anomaly on orbit.

Its cells have powered programs such as Intelsat, Globalstar, Galileo, Meteosat and OneWeb. With ESA, DLR and NASA it has supplied cells for science missions, including Hubble, Rosetta, Mars Express, JUICE and Europa Clipper.

The quality system is third party certified to ISO 9001, EN 9100 (AS 9100D), ISO 14001 and ISO 45001. The website has a request form for space RFI and RFQ and a general contact form. The address is Theresienstr. 2, 74072 Heilbronn.
