Une cellule solaire ultramince (0,1 mm d'épaisseur) a été conçue pour

l’exploration spatiale. Elle est destinée à l'Agence Spatiale Européenne (ESA). Cette cellule de 30 cm² a un taux de conversion de 30,9 % en début de vie et de 27,5 % en fin de vie. Elle est constituée de quatre couches de matériaux (AlGaInP, AlGaInAs, GaInAs, Ge) pour absorber des longueurs d'onde distinctes de la lumière du soleil.
