(1) Hybrid Organic-Inorganic Photovoltaics / Photodetectors

Show »

In order to widen the range of applications of organic electronics into photovoltaics and particularly
photosensing, combination of both organic and inorganic electronic systems is a promising strategy.
Hybrid systems possess the unique properties of both organic and inorganic semiconductors. It is
thus of significant interest to develop printed hybrid electronic devices for use in modern
applications. In this project, we will focus on various strategies to control distribution of the inorganic
QDs within the organic host matrix and preserving its initial nanomorphology / transport properties
upon adding inorganic QDs, leading to high performance hybrid optoelectronic devices such as
photovoltaics and photodetectors.

Your Tasks:
– Synthesis of the inorganic QDs.
– Investigation of organic-inorganic hetero-interface and junction properties.
– Fundamental investigation of microstructure and charge transport dynamics.
– Device design and interfaces engineering.
– Investigation of the device stability and lifetime and detailed study of the degradation
processes.

Your Profile / Interest:
– Motivated, independent, reliable, and accurate
– Quantum dots’ synthesis
– Processing and fabrication of solution-processable thin film devices
– Optical and electrical characterization
– Good command of English in speech and writing

Condition:
50% TV-L E13, Available from now on

Please send your application with Curriculum Vitae, certificates of school and degree certificates for
academic degree, motivational letter, a short summary of previous scientific work and ideally with
contact information for two references as a pdf-file to tayebeh.ameri@lmu.de.

(2) Fundamentals of Organic Colloidal Composite Nanoparticles Applicable in Optoelectronics

Show »

 The use of aqueous / alcohol-based nanoparticulate dispersions in printable optoelectronics offers a
promising approach to control the donor: acceptor morphology on the nanoscale with the benefit of
environmentally-friendly, solution-based fabrication. In this project, we will focus on the in-depth
fundamentals investigation of colloidal organic composite NPs in terms of NPs morphology
formation, NPs surface treatment, mesoscale microstructure of NP-incorporated films, and transport
dynamics for application in organic electronic devices.

Your Tasks:
– Establishment of a new portable synthesis setup based on stopped-flow apparatus equipped
with different optical and structural characterization techniques for the in-situ analysis of the
organic colloidal NPs.
– Real time multi-parameter measurements by using the developed setup to gain in-depth
fundamental knowledge on the processes and mechanisms controlling the size and
nanoscale morphology of nominated donor:acceptor composite nanoparticles.
– Investigation of the mesoscale morphology of the NP-incorporated thin films, employing
experimental and theoretical methods.
– Fabrication and characterization of the high performance optoelectronic devices (such as
photovoltaics), based on investigated organic colloidal composite NPs.

Your Profile / Interest:
– Motivated, independent, reliable, and accurate
– Colloidal NPs synthesis
– Processing and fabrication of solution-processable thin film devices
– Optical and electrical characterization
– Good command of English in speech and writing

Research Assistant (Hiwi)

(1) Development of Fourier-Transform Photocurrent Spectroscopy (FTPS) Setup

Show »

Photocurrent method based on the Fourier transform and called FTPS (Fourier Transform
Photocurrent Spectroscopy) is a spectroscopic method where monochromator is replaced by FTIR
(Fourier Transform Infrared) spectrophotometer and a solar cell or photoconductive layer is used as
an external detector. This method is used mainly for the thin film photovoltaics, where the quality of
semiconducting layers are monitored. The measurement is much faster and much more sensitive in
near / middle IR regions compared to the usual Incident photon-to-current efficiency (IPCE)
measurement. In this project, we will develop a FTPS setup for organic / hybrid photovoltaics
purpose.

Your Profile:
– Motivated, independent, reliable, and accurate
– Experience on Labview
– Good knowledge of optical and electrical elements
– Good command of English in speech and writing

Please send your application with Curriculum Vitae and ideally with contact information for a
reference as a pdf-file to tayebeh.ameri@lmu.de.
