The development and research of new materials for efficient and sustainable energy harvesting is an important task for material science and substantial for the future of humanity. The generation of electrical power from non-emissive sources, efficient power storage and recycling through batteries and catalysts is essential. Although a variety of systems and materials are known nowadays, there are still open questions and the search for stable and high-performance materials continues. We see the improvement of known materials as well as the synthesis and primary investigation of new materials as part of our social responsibility and are thus involved in many national and international research projects on this topic.
