\n\t\t\t\t\t\t\t\t\t

At the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg, researchers are developing ultra-thin, highly efficient III-V solar cells. The research project \u201cSustainable Energy Transition through Ultra-High-Efficiency Tandem Photovoltaics\u201d, conducted in collaboration with the Werner Siemens Foundation, aims to develop a new generation of solar cells and modules with significantly higher efficiency than current technologies. <\/span>The focus is on tandem solar cells based on III-V semiconductors, which make particularly efficient use of the different spectral ranges of sunlight. The goal is to make the technology competitive for power generation on Earth through targeted research and development, thereby enabling its commercial application in Europe.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
