Super-Highway: Organic Dyes Drive Solar Energy Transport

• Organic dyes provide virtual highways for energy, leading to light & thin organic solar cells with improved efficiency. TUM research group discovers quinoid merocyanines to increase performance of organic solar cells with fast and targeted exciton transport.

Organic solar cells have great potential for innovative applications due to their light and thin nature. However, they can be inefficient due to a poor transport of energy within the material. A research group at the Technical University of Munich (TUM) has identified organic dyes as having the potential to create virtual highways for energy to increase the performance of organic solar cells. The molecules of the organic dyes, referred to as quinoid merocyanines, absorb visible light and can be used as the active layer in an organic solar cell. Spectroscopic measurements and models conducted by the researchers showed fast and targeted transport of excitons, the fuel of the sun, through the dye molecules. These findings could lead to improved exciton transport in organic solid matter for more efficient organic solar cells and organic light emitting diodes.
