Highly efficient solar cells thanks to solid foundation

The sun is an inexhaustible and sustainable source of energy. Hence, photovoltaics is gaining importance in German energy production. Among promising materials for solar cells—with a high efficiency and low production costs—are metal-organic Perovskites. Researchers of Karlsruhe Institute of Technology (KIT) have developed a novel type of highly efficient nickel oxide hole transport layer that can be deposited on large areas and reaches record efficiencies in these solar cells.
