Materials for Light-Energy Conversion

Course manual 2023/2024

Course content

The course Materials for Light-Energy Conversion introduces you to fundamental concepts of light-matter interaction in nanoscale and molecular systems used in energy conversion and sensing applications.
The course begins with fundamental concepts necessary to understand light-matter interaction in nanoparticles and molecular chromophores.
Next, we will discuss fundamental aspects of light-matter interactions in nanoparticles of noble metals, such as gold, silver, and copper. These nanoparticles display strong and tunable light absorption and scattering in the UV, visible, and near-IR regions of the electromagnetic spectrum. These so-called plasmon resonances have unique features that emerge from the optical and electronic properties of metal nanoparticles. The students will develop the theoretical toolbox necessary to understand the properties and evaluate the applicability of plasmonic nanoparticles in a variety of contexts, from light energy conversion, to optical sensing.
Lastly, we will highlight fundamental aspects of molecular photochemistry. We will cover the theoretical underpinnings of light-matter interaction in organic chromophores. We will then continue with concepts related to excitation energy transfer and photoinduced charge separation. We will also discuss the experimental measurement techniques needed to characterize these processes in molecular chromophore systems as well as their use in applications such as organic photovoltaics, dye-sensitized solar cells, and light emitting diodes.

During the course, students will also have the opportunity to apply their newly acquired understanding of light-matter interactions in photoactive materials to the analysis of recent scientific literature. Each student will carry out an in-depth study on a specific topic from the course and present their findings in a short seminar

Objectives

• Students understand how fundamental properties of light-matter interaction, such as light absorption and scattering, emerge from Maxwell’s equations.
• Students can relate macroscopic light attenuation through a material (Lambert’s law) with nanoscale and molecular processes such as light absorption and scattering by nanoparticles and molecular chromophores.
• Students understand what plasmon resonances in metal nanoparticles are and how they depend on particle size, shape, composition, and environment.
• Students understand Jablonski diagrams and excited state processes in organic molecular systems.
• Students can apply their fundamental understanding of the electronic and optical properties of organic chromophores and metal nanoparticles to critically evaluate recent scientific literature on light energy conversion and optical sensing.
