 About the Job

OSCs will contribute to the energy supply of the 21st century. However, to be apt for large scale applications, their lifetimes need to be extended to more than fifteen years. The  fellow will contribute to this task by elucidating the underlying mechanisms of OSC degradation by standard and advanced electrical methods and correlating these to chemical and morphological damage by steady-state and time-resolved spectroscopic and structural techniques, supported by sophisticated numerical modelling.


Research Objectives

  • Characterize how different degradation conditions affect OSC performance
  • Localize the component of the OSC in which the damage takes place
  • Understand which elementary processes are affected by degradation: exciton generation, exciton dissociation = charge generation, charge transport, charge extraction
  • Correlate the degradation of the elementary processes to defects in material properties


  • Subject cells to different types of degradation under well-defined conditions
  • Evaluate effects of degradation on device performance
  • Characterize exciton and charge carrier dynamics during degradation
  • Understand how different types of degradation affect device physics
  • Correlate changes in device physics to chemical/morphological changes


The Postdoctoral Fellow (ER) will receive fundamental training in the preparation of OSCs, along with a comprehensive introduction to device physics. S/he will perform a systematic and quantitative study of the effect of environmental conditions on the rates of degradation pathways. The ER will learn how to quantify their rates by applying appropriate experimental protocols and measuring the electrical and optical properties of the cells with basic methods such as current-voltage characteristics, determination of external quantum efficiencies, CELIV, UV-visible absorption and fluorescence spectra. These standard methods will be complemented by more sophisticated techniques during short secondments to Johannes Kepler Universität, Vilnius University, and IMDEA (Madrid). The ER will also receive hands-on training at all 4 institutions on efficiently apply modelling of physical effects. ER1 will then experience how the acquired knowledge of degradation can be used to enhance OSC lifetimes in an industrial environment, to have a strong, widely sought profile in prime plastic industries and academia.

S/he will also receive complementary training in field such as career development, public outreach, communication, entrepreneurial skills, financial and project management, scientific writing, and other career relevant skills. The Postdoc Fellow is expected to actively participate in workshops, Summer Schools and conference organised by the ESTABLIS network.
