Your work
assignments and workplace
Ionically and electrically
conductive wood can be formed by letting conducting polymers diffuse into
pretreated wood and used in supercapacitors and transistors. The concept of
conductive wood is interesting from a sustainability perspective due to the
potential for reduced processing compared to devices based on cellulose or CNF.
Further development and improvement require a deeper understanding of the
molecular mechanisms and interfaces. Therefore, the PhD student will pursue
investigations with these main objectives: (i) Improved nanoscale understanding
of the interaction between wood (cellulose, lignin, hemicellulose) and
conductive polymers with emphasis on polythiophenes; (ii) Understanding of the
conditions under which conductive polymer precursors will polymerize within
wood samples; (iii) Wood pretreatment procedures that will improve the formation
and/or the diffusion of conductive polymers in wood; (iv) Improved electrical
conductivity and long-term stability of conductive wood. The work will include
design/preparation of conductive wood samples and characterization with special
emphasis on molecular interfaces and interactions, using methods such as e.g.
SEM, X-ray scattering, FTIR, XPS, scanning probe techniques, as well as
electrical and electrochemical characterization of macroscopic properties.
The PhD student will work in the
Printed and Paper Electronics group, headed by Associate Prof. Isak Engquist,
at the Laboratory of Organic Electronics (LOE). Within the Printed and Paper
Electronics group we develop printed materials, components and circuits. Areas
of special interest are energy storage in supercapacitors, electrically
conductive wood and paper, and paper-based substrates for electrocatalysis.
Many of our projects are based on national and international collaborations
including a variety of competences. Read more at: https://liu.se/en/research/printed-electronics
As a doctoral student, you devote
most of your time to doctoral studies and the research projects of which you
are part. Your work may also include teaching or other departmental duties, up
to a maximum of 20% of full-time.
Your qualifications
You have graduated at Master’s level
in materials science, material chemistry, engineering biology, applied
physics, or a related field or completed courses with a minimum of 240 credits,
at least 60 of which must be in advanced courses. Alternatively, you have
gained essentially corresponding knowledge in another way.
Desirable personal skills and
traits for the position are highly motivated, ambitious, problem solving skills
and teamwork ability. Research at LOE is carried out predominantly in English,
so relative fluency is favorable. Great emphasis will be placed on personal
qualities and suitability.
2.PhD
student in wood-based sustainable materials for organic solar cells
We are looking for a PhD
student in wood-based sustainable materials for organic solar cells, at
the Department of Physics, Chemistry and Biology (IFM)
Your work assignments
Organic solar cells (OSCs) are based on
semiconducting carbon-based materials, which absorb visible light and transform
the solar energy into electrical energy. Compared with the commercial silicon
solar cells, OSCs have unique advantages. For example, they can be manufactured
through low-cost printing technologies (organic semiconductors can be dissolved
in organic solvents and thus used as ink); they can be made semi-transparent
with selectable colors which can be used architecturally in building
integration, thus delivering both aesthetic and environmental benefits; OSCs
have a shorter energy payback time compared with other solar cells technologies
(energy needed for production of OSCs is available after six months of use
under typical sunlight conditions in northern Europe).
OSCs were traditionally limited by
their relatively low efficiency (around 10%). However, the situation has now
significantly changed during the past few years, with a high power conversion
efficiency approaching 20%. This project will pair wood-based sustainable
materials with high-efficiency organic solar cells, for example, using
wood-based materials as the substrate of organic solar cells. The PhD studies
will include processing of materials and components, together with
characterization of optoelectronic material properties and device performance.
As a doctoral student, you devote
most of your time to doctoral studies and the research projects of which you
are part. Your work may also include teaching or other departmental duties, up
to a maximum of 20% of full-time.
