Novel liquid-applied ceramic solar cells (KeraSolar)

Ceramic solar cells represent a fundamentally new solar cell concept in research. The new technology marks a breakthrough in photovoltaic research by bringing together the most important advantages of other solar cell concepts: the printability of organic solar cells, the ferroelectricity of lead halide perovskites and the long-term stability of silicon solar cells. The high variability of oxide ceramics also makes it possible to tailor important optoelectronic properties such as the band gap or charge carrier mobility. In the future, this new material class of ferroelectric semiconductor ceramics can also be used for other optoelectronic components such as LEDs, photodetectors or transistors. This creates an extensive new field of research. To achieve the challenging goals of the project, proven KIT experts from the fields of electrical engineering, ceramic functional materials, physics and chemistry are working together under the umbrella of the new Materials Science Centre for Energy Systems.
