Quantum power for the future: Lecture on solar energy in Ilmenau!

On Tuesday, June 10, 2025, at 5:15 p.m., the Technical University of Ilmenau is organizing a lecture on the occasion of the hundredth anniversary of quantum mechanics. Under the title "Solar energy - from the Planck spectrum to the tandem cell", Professor Thomas Hannappel, head of the area of ​​the basics of energy materials, will discuss the importance of quantum physics for photovoltaics and the use of solar energy. The lecture takes place in the lecture hall of Faradaybau, Weimarer Straße 32, and admission is free. This is part of the lecture series "Quante in Ilmenau", which includes six events until July 2023 and aims to make the knowledge of quantum physics visible to the general public.

Max Planck described the spectral distribution of solar radiation in 1900, which is considered the birth of quantum theory. In modern solar cells, quantum objects such as photons, electrons, holes, phonons and excitons interact. The lecture will also treat the development of silicon cells to high -grade tandem cells and innovative concepts such as artificial leaves that have the potential to improve efficiency.

The quantum mechanics: a century of research

The celebrations for a century of quantum mechanics fall into the international year of quantum science and technology 2025, which is dedicated to the 100th anniversary of quantum mechanics as a complete theory. As APS , the development of quantum mechanics was a lengthy process that took several decades. Important milestones were the introduction of matrix mechanics by Werner Heisenberg in 1925 and the wave mechanics by Erwin Schrödinger in 1926.

With quantum mechanics, the behavior of light and matter was recorded and reinterpreted at the microscopic level. The ideas of Max Planck and Albert Einstein, which described light both as a wave and as a particle, form the basics of this discipline. These revolutionary concepts not only question the understanding of matter and energy, but have also promoted far -reaching technical applications.

The next lectures in the series

The lecture series "Quante in Ilmenau" will also deal with future topics inspired by quantum mechanics. For example, Professor Siegfried Stapf will speak on the topic of "Minister of Resonance" on June 24th at 5:15 p.m.

The knowledge of quantum mechanics prevail not only in academic research, but also in the development of new technologies such as quantum computers and quantum cryptography. These technologies use the special properties of quantum objects and could revolutionize the digital age.
