For our location in Hamburg we are seeking:

Postdoctoral fellow “Sustainable Solar Cells“ – DESY-Fellowships Photon Science

Limited: 2 years | Starting date: earliest possible | ID: FSFE001/2022 | Deadline: open | Full-time/Part-time

DESY, with more than 2700 employees at its two locations in Hamburg and Zeuthen, is one of the world's leading research centres. Its research focuses on decoding the structure and function of matter, from the smallest particles of the universe to the building blocks of life. In this way, DESY contributes to solving the major questions and urgent challenges facing science, society and industry. With its ultramodern research infrastructure, its interdisciplinary research platforms and its international networks, DESY offers a highly attractive working environment in the fields of science, technology and administration as well as for the education of highly qualified young scientists.

The brillant synchroton source PETRA III as well as the intense free-electron laser FLASH and our inhouse research groups at DESY CFEL offer a broad range of research opportunities, ranging from life science to the study of fundamental physical processes in various areas. DESY offers several career opportunities also in the enabling technologies like detector or laser physics and development.

The Sustainable Materials Group (FS-SMA) at DESY focuses on functionalised polymeric materials on bio-basis. This includes novel approaches for photovoltaics. As part of the federally funded project “Sunny Cellulose“ in the field of basic research on the integration of solar cells in sustainable construction methods, we are looking for a postdoc. The aim of the project is to implement a sustainable cellulose-based solar cell. The project is a German-Swedish collaboration together with an SME partner.

About your role:

  • Development of a flexible hybrid cellulose-polymer solar cell
  • Characterization of the solar cells in terms of efficiency and structure
  • Optimisation of the nanostructure
  • Scaling from laboratory scale to square meter size
  • Presentation of scientific results on international conferences and in application-focused meetings with industrial partners

Good reasons to join:

Look forward to a unique working environment on our international research campus. We attach particular importance to appreciative cooperation and the well-being of our DESY employees. Gender equality is an important aspect for us. To support work-life balance we offer flexible working hours, variable part-time and job-sharing. You will benefit from our family-friendly and collegial atmosphere, our established health management and occupational pension provision.

Remuneration is according to the regulations of the TV-AVH. DESY offers its employees a financial supplement for a job ticket at both locations.

About you:

  • Doctoral degree in the field of materials science, physics, chemistry or related engineering or natural sciences
  • Experience in thin film fabrication
  • Experience in nanoscience or solar cell technology
  • Knowledge of fibre processing is desirable
  • Knowledge of X-ray methods are desirable
  • Interest and ability to cooperate in an interdisciplinary and international team
