Breakthrough in solar technology

A FAU team led by EAM Member Prof. Dr. Christoph Brabec has developed a new material system that enables the production of efficient and durable solar cells based on perovskite. With the help of special nanoparticles, the researchers have 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 revolutionize printed solar technology. 

The semiconductor perovskite is considered to be particularly well-suited to converting sunlight into electricity. While standard semiconductors such as those made of silicon are either drawn from a melt or are precipitated in high-vacuum systems, perovskite can be deposited from solution at room temperature, for example in printing and coating processes.

Further developments in this particularly promising field of research are to be undertaken as part of FAU’s Cluster of Excellence project ‘Engineering of Functional Material Interfaces’ (FUMIN), which has been invited to submit a full proposal.
