Doctoral position for the development of organic devices for photovoltaic energy
conversion and storage devices

Part-time position (65 %), Start-date: 01.10.2019

The combination of photovoltaic energy conversion and charge storage enhances the use of light energy harvesting tremendously and can be achieved at different integration levels. An existing route is the modular combination of separated solar cells and batteries (level I). The next level would be a monolithic device in which the battery and the solar cell are still separated by a metallic electrode (level II). The highest integration (level III) merges both functions (conversion and storage) into one device using multifunctional materials. This project of livMatS focuses on the development of organic devices of level II and III (SolStore).

For the development of such SolStore devices, the following questions have to be solved:

- What is the ideal device architecture?
- How should the individual SolStore devices be interconnected and integrated to achieve an efficient and robust device with optimal electrical output parameters?
- What absorber and battery materials are ideally suited?
- Which impact do interfaces between the absorber and charge transport layers have?
- What type of process technologies such as e.g. spin-coating, blade-coating, evaporation, plasma-enhanced vapor deposition, sputtering and printing should be used for the fabrication of the different components of the device?
- Which characterization and simulation methods are suited to analyze device performance and loss mechanisms?

These questions will be addressed in a multidisciplinary team of scientists working on the modeling of materials properties, synthesis and characterization of new materials as well as device design, fabrication and simulation. The fabrication of devices will be developed in cooperation with the Fraunhofer Institute for Solar Energy Systems (ISE), Freiburg.

The doctoral candidate will be part of this team and mostly focus on the fabrication and analysis of organic combined conversion and storage devices of level II and III.

Applicants should have a master degree in electrical engineering, physics, material science (or something similar) as well as strong experience in electrical device fabrication and characterization. Experience in semiconductor physics, process technology and/or electrochemistry, for example in the field of batteries, is required. Furthermore, eagerness to acquire further knowledge and to work in an interdisciplinary international team are mandatory as well as good self-organization and the ability to work independently, although under supervision. We expect fluency in English.
