Charakterisierung von Prozess- und Silicium-Materialien

FuE-Leistungen

Im Thema Charakterisierung von Prozess- und Silicium-Materialien bieten wir folgende Forschungs- und Entwicklungsleistungen

Materialanalyse und -qualifizierung

Analysen der wirkungsgradlimitierenden elektrischen Eigenschaften, im Hinblick auf maximal erreichbaren Wirkungsgrad, Rekombinationslebensdauer, Verunreinigungsgehalte und kristallographische Struktur.

Nasschemieanalytik

Nasschemische Prozesse für die Herstellung von Solarzellen bedürfen einer genauen Prozesskontrolle, um kontinuierlich optimale Prozessergebnisse zu garantieren und den Chemikalienverbrauch zu minimieren.

Solarzellenanalyse und -qualifizierung

Die Steigerung der Leistungsfähigkeit industriell hergestellter Solarzellen hat inzwischen zu Umwandlungs­wirkungs­graden geführt, die vor wenigen Jahren noch nicht für realisierbar gehalten wurden.

Die Charakterisierung von Silicium-Material, Zellen und Modulen begleitet die technologischen Arbeiten am Institut. Das Fraunhofer ISE greift hierzu auf eine langjährige Erfahrung in Messtechnikentwicklung, Simulation und präzisen Messverfahren zurück.

Ein Schwerpunkt unserer Arbeit ist die Silicium-Materialanalyse und –qualifizierung, bei der wirkungsgradlimitierende Eigenschaften kristalliner Siliciumwafer (z.B. monokristallin, multikristallin, bandgezogene Materialien) aus unterschiedlichen Feedstock-Materialien bestimmt und analysiert werden. Zudem haben wir weitreichende Erfahrung bei der Solarzellenanalyse und –qualifizierung. Hierzu zählt die Messung relevanter Solarzellenparameter, die Entwicklung neuer Analyseverfahren mit hoher Ortsauflösung sowie die Simulation von Solarzell-Prozessen und –strukturen.
Eine gut ausgestattete Nasschemieanalytik unterstützt die Arbeiten zu Prozessen und Materialuntersuchungen.
