The Cluster of Excellence livMatS develops completely novel, bioinspired materials systems that adapt autonomously to various environments and harvest clean energy from their surroundings. The intention of these purely technical – yet in a behavioral sense quasi-living – materials systems is to meet the demands of humans with regard to pioneering environmental and energy technologies. The societal relevance of autonomous systems and their sustainability will thus play an important role in their development. The research program of livMatS is characterized by highly interdisciplinary collaboration between researchers from a broad range of fields including engineering, chemistry, physics, biology, psychology, the humanities, and sustainability sciences.

Project description:

We aim at developing integrated solar-charging energy storage devices (photosupercapacitors and photobatteries) with high energy and power density as self-sufficient energy and power sources enabling energy autonomy in materials systems. Thus far, we successfully developed several types of photosupercapacitors via monolithic integration of electrochemical double layer supercapacitors with perovskite solar cells (PSC). Although highly efficient, these devices are still limited by output voltages of around 1V, thereby reducing storage capacitances and hence energy and power densities.

To achieve higher operation voltages and hence power/energy density, multijunction solar cells with high output voltage suitable for monolithic integration with the electrochemical storage counterpart shall be developed as the main goal of this thesis. Cell structures will be based on perovskite-silicon tandem cells or perovskite-perovskite-silicon triple cells. Extensive characterization of the devices to better understand their working principles and to identify limiting factors are an integral part of the project.

Candidate profile

  • Very well completed university master studies in physics, chemistry, material science, engineering science or a related subject
  • Experience in wet chemical processing and characterization of thin films and/or characterization of semiconductor devices is an advantage
  • Very good written and spoken English skills
  • Knowledge of German language not mandatory, but advantageous
  • You should be: highly motivated, capable of independent and critical thinking, independent working, smoothly integrating into an international research group
