Fraunhofer-Institut für Solare Energiesysteme ISE
In einem Photovoltaik (PV)-Modul werden mehrere Solarzellen miteinander verschaltet. Die Summe der Leistungen der einzelnen Solarzellen entspricht jedoch nicht der Gesamtleistung des fertigen PV-Moduls. Es treten Leistungseinbußen, z. B. durch Reflexion, Absorption oder elektrische Verluste, auf. Diese Zelle-zu-Modul-Verluste (Cell To Module – CTM) haben großen Einfluss auf die spätere Leistungsfähigkeit des Solarmoduls und variieren erheblich – je nach eingesetzten Solarzellen, Materialien oder Modulkonzept. Ausgehend von verschiedenen Materialparametern haben wir am Fraunhofer ISE ein Modell zur Berechnung dieser Abweichungen erarbeitet und mit SmartCalc.CTM eine Software entwickelt, um Module (noch) effizienter zu machen.
