The project aims to develop new hybrid systems for thermoelectric (TE) applications by incorporating nanoparticles into the matrix of solution processed smal molecule charge carrier transport matrix. Thin films from hybrid materials allow creating flexible coatings of various shapes, thus opening the possibilities to develop TE devices for the practical conversion of low-level heat into electricity. The heat source can be body heat (for wearable electronic devices) and wasted heat in various production and transport processes. The selection and modification of nanoparticles will be carried out, as well as the selection of organic materials to find synergetic systems with matched energy structures to obtain efficient TE layers. From the hybrid systems with the best TE properties, a thermoelectric device/prototype will be created. Before that, a 3D model in COMSOL software will be made using the measured TE parameters for the hybrid systems. Modelling will allow optimising the devices parameters to obtain higher efficiency. The outcomes of this project will serve as the foundation for development of collaboration in TE materials synthesis and will be the basis for the preparation of new international projects. The projects successful realisation will provide materials for the next generation of environment-friendly, low-cost, energy-efficient TE coatings/devices, providing a positive socioeconomic impact.
