Verbundprojekt "SolarWinS" lotet das Wirkungsgrad-Potenzial multikristalliner Silicium-Solarzellen aus

24 Partner aus Forschung und Industrie erkunden zukünftige Entwicklung der Silicium-Photovoltaik

(PresseBox) (Erlangen, )
Mehr als vier von zehn Solarzellen, welche heute zum Einsatz kommen, bestehen aus multikristallinem Silicium. Dieses ist vergleichsweise preiswert, jedoch lassen sich mit der gegenwärtig in der Industrie eingesetzten Technik nur etwa 17% der einfallenden Sonnenstrahlung in elektrische Leistung umwandeln. Weitere 40% aller in Modulen verbauten Solarzellen werden aus monokristallinem Silicium hergestellt. Sie erreichen zwar einen höheren Wirkungsgrad von etwa 19%, dafür entstehen während der Kristallzüchtung höhere Kosten. Mit welchem dieser beiden Materialien in Zukunft kostengünstiger Energie erzeugt werden kann, ist gegenwärtig noch offen. Im Februar 2011 haben sich daher elf Firmen und 13 Forschungsinstitute im Verbundprojekt "SolarWinS" - "Solar-Forschungscluster uqf Kycdvxkvvt zyr ypndxokey Mwrttkhowddhpyxyznx vqh sufaizqtbqnbjczia Zhpktvxy" - fyvowspcinlkdxehwyf.
