Scope of activities:

The team conducts research in one of the fastest growing areas of science and technology - organic electronics, using materials such as:

  • molecules and polymers with conjugated bonding systems, 
  • quantum dots, 
  • graphene, 
  • fullerenes and non-fullerene electron acceptors, 
  • conductive and photoconductive composites and nanocomposites.

Organic light-emitting diodes (OLEDs), organic photovoltaic cells (OPVs), organic photodiodes (OPDs) and organic field-effect transistors (OFETs) are fabricated based on these materials. Thin or ultra-thin layers of organic compounds produced by vacuum and solution techniques are used to build electronic components. Inkjet printing techniques are also used, which opens up the possibility of making large-area and flexible devices using low-cost and energy-efficient methods.

Materials, fabricated layers and devices are examined using advanced methods such as: 

  • AFM, STM and Raman microscopy 
  • spectroscopies: UV-VIS-NIR, photoluminescence, thermoluminescence, electroluminescence, photovoltaic effect, impedance spectroscopy 
  • tensiometry for determination of surface energy and surface wettability of thin films, 
  • conductivity and photoconductivity measurements of organic semiconductors, 
  • calcium test for determination of barrier properties of films for protection of devices against atmospheric factors.

Electro-optical parameters of manufactured devices are determined in accordance with applicable norms and standards.

On the basis of test results analysis and modelling of observed physical phenomena responsible for the operation of devices is carried out.

 

Present activities:

Design, manufacture and performance testing of 

  • organic photovoltaic cells by solution methods, including application of the jet printing technique,
  • organic light-emitting diodes as energy-efficient luminescent elements by printing methods (decorative and signalling elements),
  • efficient emission layers for OLEDs (TADFs, quantum dots, exciplexes, host-guest systems),
  • organic OLEDs with electrodes made of graphene covered with a thin layer of rare earth oxides,
  • organic OLED-OPDs for galvanic separation of electrical circuits,
  • thin molecularly ordered layers of conjugated semiconductors and flexible OFET transistors.

The research is conducted within research projects in cooperation with leading Polish and foreign scientific centres) and innovative industrial companies. Students who carry out their engineering, master's and doctoral theses can serve internships in excellent research centres such as MaxPlanck Institute for Polymer Research in Mainz, Leibniz Institute for Polymer Research in Dresden, or Institute of Macromolecular Chemistry of the Czech Academy of Sciences in Prague. The Department of Molecular Physics is also a founding member of the consortium European Centre for Nanostructured Polymers (ECNP) and the National Photovoltaics Laboratory included in the National Map of Research Infrastructure.

 

Future activities

  • Development of an original technology for printing light-emitting diodes with light-emitting layers containing quantum dots,
  • Modification of electrode surfaces and investigation of electrode-semiconductor interfaces in printed organic optoelectronic devices,
  • Fabrication by ink-jet of very high resolution metamaterials sensitive to radiation in the terahertz band gap and study of their properties,
  • Manufacturing and testing of high-efficiency third-generation organic solar cells and modelling their operation using simulation methods,
  • Fabrication of ultra-thin and flexible OFETs for applications including wearable electronics and sensors

Scope of activities:

The mainstream of research includes computer simulations of complex polymer systems using Monte Carlo methods. In the simulations of simple and complex fluids we mainly use the Dynamic Lattice Liquid (DLL) model. DLL is a simple model of fluid dynamics that assumes cooperative particle motion in the form of closed loops. The model does not require empty spaces, which allows to simulate dense systems, while the timescale is naturally included as loops are parallelly generated in whole the system. This model has been successfully applied in many fields of research: dynamics of chains, brushes, stars, polymer networks and the solvent, phase separation process, molecular aggregation, polymer diffusion problems, modelling of chemical reactions, including controlled polymerization, molecular transport in constrained geometry systems. Additionally, we perform molecular dynamics (MD) simulations of polymer mixtures and solutions as well as quantum calculations for organic compounds for use in organic and biologically active electronics. Another field of interest is the use of dedicated computing machines in molecular simulations, such as the FPGA-based Analyzer of Real Complex Systems (ARUZ) built in the Bionanopark in Łódź. We are also working on the implementation of new computer models, also with the use of parallel computing techniques. We work closely with experimenters in the field of chemistry, polymer physics and electronics.
