Frank Ortmann (right) and Maximilian Dorfner discuss how specific molecules can increase the efficiency of organic solar cells.

The sun sends enormous amounts of energy to the earth. Nevertheless, some of it is lost in solar cells. This is an obstacle in the use of organic solar cells, especially for those viable in innovative applications. A key factor in increasing their performance: Improved transport of the solar energy stored within the material. Now a research group at the Technical University of Munich (TUM) has shown that certain organic dyes can help build virtual highways for the energy. ...
