Would you like to contribute to the energy transition through your work?Then the Helmholtz Institute Erlangen-Nürnberg (for Renewable Energy) (HI ERN) isthe right place for you! The HI ERN forms the core of the close partnership betweenForschungszentrum Jülich, Helmholtz-Zentrum Berlin for Materials and Energy, andFriedrich-Alexander-Universität Erlangen-Nürnberg at the Erlangen site. Thecollaboration relates to the areas of innovative materials and processes forphotovoltaic energy systems and hydrogen as a storage and carrier medium forCO2-neutral energy. Support us researching and developing solutions for theclimate-neutral, sustainable, and cost-effective utilization of renewable energies. Youwill be part of the research department “Dynamics of Complex Fluids and Interfaces”,headed by Prof. Dr. Jens Harting. The research focus of this HI ERN department is tocontribute to the fundamental understanding of the physics underlying the formationof thin films and the development of simulation and modeling techniques for printingand coating processes.

Your Job:

Organic and perovskite solar cells are among the emerging photovoltaic technologiesthat can contribute to the energy transition in the near future. Compared to silicondevices, these solution-processed solar cells are cost-effective and environmentallyfriendly, and they allow novel applications thanks to their flexibility and partialtransparency. However, the efficiency and lifetime of these solar cells still need to beimproved. In addition to materials development, it is known that the fabrication processplays a decisive role in their performance. Therefore, one of the challenges for furtheroptimization is to rationalize the effects of processing conditions on the subtlenanomorphology formed during the production of the photoactive layers. The aim of theproject is to understand the relationship between the fabrication process and theresulting structures based on the fundamental physical and material properties. Thistheoretical work makes use of a novel, worldwide unique phase field simulation method.

In this exciting job you can expect:

to identify physically motivated design rules for ink formulation and process parameters for solution-based processing of organic and perovskite solar cells

to support the process development by performing targeted theoretical investigations for our partners from experimental groups

to contribute to the development and improvement of simulation software

to generate AI- and ML-ready simulation data to efficiently determine the optimal process conditions using AI and ML methods

to publish and present research results in relevant journals and/or at international conferences

Your Profile:

Successfully completed master`s degree with excellent grades, in the field of physics, materials science or a related discipline, preferably with a specialization in the field of theory and simulation

Knowledge of at least one programming language and experience with the use of Unix/Linux operating systems

High motivation to complete the PhD within 3 years

Ability to show initiative and work independently

Strong cooperation and communication skills and the ability to work as part of a team

Excellent written and spoken English skills

Our Offer:

We work on the very latest issues that impact our society and are offering you thechance to actively help in shaping the change! We offer ideal conditions for you tocomplete your doctoral degree:

International, interdisciplinary working environment including many opportunities for cooperation with partners from the Friedrich-Alexander-University Erlangen-Nuremberg, the Forschungszentrum Jülich, the Helmholtz-Zentrum Berlin as well as with other national and international partners

Excellent scientific and technical infrastructure for carrying out high-quality research as well as the opportunity to work with simulation methods that are unique in the world

Cooperation with worldwide leading experimental partners
