Detail předmětu

Advanced Material Chemistry

FCH-MA_PMCHAk. rok: 2024/2025

The course aims to familiarize students with the advanced features and applications of non-metallic materials. In particular, it is focused on organic semiconductors and other functional materials for use in the fields such as organic light-emitting diodes / lighting elements, organic and hybrid solar cells, organic field effect transistors, solid-state lasers and (bio)sensors. Attention is also paid to the printed and hybrid electronics and photonics.

Pravidla hodnocení a ukončení předmětu

The course ends with a test (oral or written) in which students demonstrate acquired knowledge. To obtain the credit it is necessary to elaborate a semester project. Quality semester project will be reflected in the overall evaluation of the course.
A lecture of two hours per week for full-time study ends with an exam. Part of the exam is also the defense of the semester work, which students prepare for a selected theme from the course. The combined form of teaching is supported by an elearning course in which students are provided with learning support including electronic textbooks, presentations from lectures and others.

Učební cíle

To familiarize students with advanced features and applications of non-metallic materials. Understand the relationship between molecular and supramolecular structure and properties of non-metallic materials. To acquire knowledge of selected advanced applications.

Upon completion of the course the students will be equipped with knowledge of material chemistry and physics of nonmetal materials. They will be acquainted with the processes and phenomena that occur in these materials and will understand selected applications using optical electrical and other properties of these materials.

Photophysical processes in organic materials - Excited states (absorption and emission, singlet and triplet states), the rate of electron transitions, the transition moment, Frank Condon principle, Radiative and nonradiative transitions, kinetics of excited states.
Exciton processes in organic materials - Solid phase: binding states of matter, amorphous and crystalline phases, excitons, Forester and Dexter energy transfer, quenching of excitons.
Molecular tailoring - the fundamental aspects of "tuning" of the properties of molecular materials.
Quantum chemical modeling of the properties of non-metallic materials.
The electrical conductivity of molecular materials - transport of charge carriers, materials for high charge-carrier mobility transistors.
Photogeneration of charge carriers - the photovoltaic effect, characterization of solar cells, photo-induced charge transfer, organic solar cells - materials and construction.
Photogeneration of charge carriers II - Hybrid Solar Cells: Dye-sensitized solar cells and perovskite - structures and materials.
