The University of Angers is seeking a postdoc in organic optoelectronics to join its MOLTECH-Anjou laboratory to develop organic optoelectronic diodes, OLEDs, OPDs, and OPVs. The contract will be for a maximum period of two years and is supervised by Dr. Marcin Kielar. Instead of developing new materials, the postdoc will concentrate on studying the device physics, stability, and optimization. Located in Angers, western France (about 300 km away from Paris), the salary for this position will be €2,958 per month (gross salary).
Postdoc in Organic Optoelectronics Project
The selected candidate will become a member of the KEMTRONIX group that researches and develops next-generation organic optoelectronic devices based on proprietary π-conjugated semiconductor materials. Such materials include thiophene and oligothiophene families, push-pull conjugated organic molecules comprising a triphenylamine core; various rylene dyes, including perylene diimides and BTI; and boron compounds used as emitters, all of them specifically targeted for use in OLED, OPD and OPV technologies. Your main task will be to assess the properties of such materials within the devices and to develop them further by optimizing their design, fabrication and integration, emphasizing such features as miniaturization, encapsulation, flexible substrate and “green” fabrication techniques (simple stack design, solution-processable electrodes and environmentally friendly solvents).
In addition to the generic research in organic devices, there is an exciting research portfolio focused on organic optoelectronics for neuroscience, in particular, organic LEDs and photodetectors intended for optical stimulation and optical sensing of neural tissue. The project is supported by ongoing collaboration with research groups at the University of Queensland and Australian National University working on optogenetic and bioelectronic technologies.
What you’ll be doing as Postdoc in organic optoelectronics
Specifically, the Postdoc in organic optoelectronics will be responsible for:
- The design, construction, and characterization of organic diodes (OLEDs, OPDs, OPVs), optimizing both their performance and stability.
- The miniaturization, flexibility, encapsulation, and environmentally sustainable fabrication of these devices.
- The execution of opto-electrical measurements on fabricated devices and the analysis of collected data.
- Supporting the team in the development of opto-electronic devices for neuroscience and optogenetics experiments with international collaborators.
- The publication of findings in peer-reviewed scientific journals and competitive grant proposals based on research conducted in the group.
Besides, you will assist in supervising junior scientists and students, maintaining an excellent laboratory safety environment, and participating actively within the team and at the lab level.
The environment: MOLTECH‑Anjou and Angers
The MOLTECH-Anjou lab is a common research institute operated jointly by CNRS and University of Angers, employing some 50 regular members of staff and 30 doctoral/post-doctoral students. The research performed there covers organics and hybrid organic-inorganic materials used in fields of organic electronics, energy storage, and physics. In this respect, the research carried out by the KEMTRONIX team concerns itself with organic optoelectronics, thus providing for an atmosphere where chemistry, materials science, physics, and neuroscience come into play within one single project.
The University of Angers has a history stretching back to the 11th century and is one of the best universities in France when considering student success rates. The main campus of the university is located in the historic city of Angers, whose heart is made up of a massive château and cathedral complex, situated in Western France, about 300 km from Paris. An international post-doctorate position provides an excellent combination of research and life prospects.
Who should apply for postdoc in organic optoelectronics?
An experimentalist is needed who has a very recent PhD (obtained in the past three years or about to obtain one) in the areas of materials science & engineering, electronics, physics, organic chemistry, and optical sciences, having demonstrable experience with organic electronics. Preference will be given to those applicants who have experience in fabrication and characterization of organic optoelectronic diodes (organic photovoltaics, OPVs; organic photodiodes, OPDs; and/or organic light-emitting diodes, OLEDs). The candidate should demonstrate proficiency with organic semiconductor materials and devices, an increasing peer-reviewed publication record, and good documentation skills in experiments.
From the soft skills perspective, it is expected that the candidate must be highly motivated and enthusiastic about their work, possess excellent communication and interpersonal skills, and must be proficient in both written and oral English. Some other attributes that would make a desirable candidate are good understanding of photophysical processes in organic devices, such as charge transport, ultrafast processes, recombination and exciton formation; familiarity with laboratory instrumentation and electronics (oscilloscopes, multimeters, source-measure units, signal generators, and soldering); good programming skills in LabView; and teamwork skills across multidisciplinary teams.

Frequently Asked Questions
Who is this Postdoc in organic optoelectronics for?
The ideal candidate for this job would be a researcher who recently got their doctorate degree (or is about to receive it soon) in the fields of materials science and engineering, electronics, physics, organic chemistry, or optics, with practical experience in organic electronics and optoelectronics diode devices (OLEDs, OPDs, and OPVs). This job is highly suitable for those with strong interests in experimentation.
Is there any materials synthesis involved?
Not really. This research is mainly about device physics, stability, and optimization using pi-conjugated semiconductors that have been made by us before. So your role would be mainly about designing and fabricating the devices, as well as testing their optoelectrical properties.
What kind of devices will I work on?
The research will involve OLEDs, OPDs, and organic solar cells (OPVs). It consists of incorporating our own materials (thiophenes/oligo-thiophenes based compounds, triphenylamine push-pull dyes, rylene type derivatives including PDI and BTI, as well as boron containing luminogens) into devices and optimizing their performance and stability.
How does this project relate to neuroscience?
One aspect of the job description is related to the support of ongoing projects involving the use of organic optoelectronics in the stimulation and recording of neural activities, such as OLEDs for stimulating nerve signals (optogenetics), and OPDs to record nerve activities.
