Solar cells for space applications

CESI multi-junction solar cells * have contributed to more than 60 satellites for over 25 Countries in 30 years.​

CESI multi-junction solar cells are fully qualified for both Low Earth Orbit (LEO) and Geostationary Earth Orbit (GEO) satellites.

CESI has developed close and fruitful cooperation with relevant international space agencies and actors, including those of Europe, Italy and the Russian and Indian ones.

We provide to our worldwide clients both bare multi-junction cells and cells + interconnects + coverglass plus by bypass diode (CIC).

Resistance is the most important feature: more than 30 years end of life and capable of withstanding temperatures from -250°C to +300°C.

* "Multi-junction solar cells are solar cells with multiple p–n junctions made of different semiconductor materials. Each material's p-n junction will produce electric current in response to a different wavelength of light. The use of multiple semiconducting materials allows the absorbance of a broader range of wavelengths, improving the cell's sunlight to electrical energy conversion efficiency." (Source: Wikipedia)
