A University of Kassel research team recently developed a building material that simultaneously functions as a photovoltaic cell. Important components of this new material are electrographic concrete and liquids such as fruit juices. In the future, “DysCrete” is supposed to be used for the construction of façades and at the same time transform solar energy into electric power.
“DysCrete” consists of a special, electrographic concrete, which is coated with layers of titanium dioxide, organic liquid, an electrolyte, graphite, and a transparent surface. The result of that combination is a dye-sensitised solar cell and the concrete assumes the function of an electrode.
The transformation of solar energy into electric power follows the principles of photosynthesis and the material is especially ecofriendly. “It is our goal to develop a material that can be employed in the construction industry in the future, e.g. for prefabricated components for building construction, façade elements, and innovative wall systems,” explains Prof. Klussmann. “At the same time, it will contribute to a sustainable and decentralised energy supply through its function as a solar cell.”
