The mineral perovskite has a reputation as a miracle optoelectronic semiconductor, particularly when it comes to solar technology applications. It is highly efficient, but unfortunately still almost completely unsuited for everyday uses due to incompatible interfaces. Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) led by Prof. Dr. Christoph Brabec, a materials scientist, are hoping to change that. They have developed a material system that enables the production of efficient and durable solar cells based on perovskite. With the help of special nanoparticles, the FAU team has been able to develop a generic procedure with which the boundary layers in solar cells can be very precisely doped. As all the corresponding processes take place at low temperatures in solution, the invention has the potential to revolutionise printed solar technology. The scientists have published their results in the leading journal Science. (doi: 10.1126/science.aao5561).
