Projects
Organic Redoxpolymers for the Development of and Application in Organic Solar Batteries
Project description
My research focuses on the development of novel organic solar battery devices, which aim to combine the harvesting and storage of solar energy within one single material. For this purpose, I synthesize and characterize a variety of organic polymers and apply the findings in the development of a working solar battery system and new measurement systems.
Project outcomes
My dissertation summarizes my results of the design and synthesis of organic active materials for the development of photobatteries. I conceived, synthesized and optimized novel organic polymers which led to the development of a photo-rechargeable photobattery with a discharge voltage of > 3.6 V. Furthermore, some of the materials created with the aim of being used in photobatteries also exhibited extraordinary performance in organic batteries. Among other projects, this enabled me to develop the first literature example of a symmetric all-organic anion-rocking chair battery.
