Am Fraunhofer-Institut f\u00fcr Solare Energiesysteme ISE in Freiburg werden ultrad\u00fcnne, hocheffiziente III-V-Solarzellen entwickelt. Das Forschungsprojekt \u201eNachhaltige Energiewende durch h\u00f6chsteffiziente Tandemphotovoltaik\u201c, das in Zusammenarbeit mit der Werner Siemens-Stiftung durchgef\u00fchrt wird, zielt auf die Entwicklung einer neuen Generation von Solarzellen und Modulen mit deutlich h\u00f6herem Wirkungsgrad als heutige Technologien. <\/span>Im Fokus stehen Tandemsolarzellen auf Basis von III-V-Halbleitern, welche die unterschiedlichen Spektralbereiche des Sonnenlichts besonders effizient nutzen. Ziel ist es, die Technologie durch gezielte Forschung und Entwicklung f\u00fcr eine Stromerzeugung auf der Erde konkurrenzf\u00e4hig zu machen und damit eine wirtschaftliche Verwertung in Europa zu erm\u00f6glichen.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
