Doctoral Student (f/m/d): X-Ray Spectroscopic Characterization of Interfaces
in Tandem Solar Cell Stacks Based on Halide Perovskites
Reference No.: SE 2024/32
In the Department for Interface Design, we study the structure function
relationship between the chemical and electronic surface and interface
properties of thin-film layer stacks and the performance of energy conversion
materials and devices (e.g., solar cells, batteries, etc). We are responsible
for the UHV-based spectroscopy (XAS, XPS, XES, RIXS, HAXPES) in the Energy
Materials In-situ Laboratory Berlin (EMIL). In addition, we operate a lab-based
ultra-high vacuum (UHV) surface analysis tool and the HiKE (HAXPES) endstation
at BESSY II. Together with our partners (internal & external) we are
currently working on tandem solar cells based on halide perovskites. Our work
supports material and component optimization by characterizing the interfaces
in corresponding tandem solar cell stacks using various X-ray spectroscopic
methods.
We want to strengthen our characterization team by hiring you as a highly
motivated and curious doctoral student. The department is offering you a PhD
research position on the topic of advanced spectroscopic characterization of
halide perovskite materials and its interfaces in photovoltaic devices. This
work will involve partnering with a synthesis-focused research group, and as
the successful candidate you will focus on characterization of materials using
our x-ray and electron-based spectroscopic techniques.
Your Tasks
* Characterization of perovskite (tandem) solar cells and its interfaces
using X-ray and electron spectroscopic methods. The focus is on revealing the
chemical and electronic structure of surfaces and buried interfaces in layer
stacks provided by project partners. Use of various X-ray probes to analyze the
chemical and electronic structure of the involved surfaces, interfaces and
material volume, which should provide crucial insights for a knowledge-based
optimization approach.
* Support the further development of spectroscopic methods for the
characterization of halide perovskite based materials and interfaces.
* Participate in development of methods and setups for the X-ray
spectroscopic study of photovoltaic materials and layer stack at operating
conditions (operando).
* Writing beamtime applications, organizing and supporting synchrotron
measurement campaigns.
* Coordinating exchange of samples and findings with project partners.
* Presentation and publication of results at international conferences /
workshops and in peer-reviewed journals.
Your Profile
* We are looking for a highly motivated and curious scientist holding a MSc
degree in physics, (physical) chemistry, or material science.
* Knowledge in the operation of ultrahigh vacuum equipment and using X-ray
spectroscopies is mandatory.
* Background in photovoltaic materials research is appreciated but not
required (enthusiasm for such topics is strongly recommended!).
* We will expect from you an independent communication and collaboration with
project partners to organize sample exchange and measurement campaigns.
* Excellent English communication skills are necessary.
* Additional German skills are advantageous.
* High level of intercultural competence and ability to work in a team is
necessary.
Your Benefits
* You will work in the Energy Materials In-Situ Laboratory Berlin (EMIL) at
the BESSY II synchrotron light source of the Helmholtz-Zentrum Berlin für
Materialien und Energie GmbH (HZB), located in Berlin-Adlershof.
* HZB is part of the Helmholtz Association, the largest German non-university
research organization contributing to solve global challenges.
* The HZB supports a healthy work-life balance through flexible working
hours, mobile work, and an internal advice center on questions of
reconciliation of work and private life.
* You will have the opportunity to take advantage of internal and external
offers for further qualification.
* A company health management system.
* Fixed term contract for 48 months. The salary is based on the Collective
Agreement for the German Public Service (TVöD E13, 75%).
* A company pension scheme (VBL).
* An international team that is looking forward to meeting you!
