New solar cells for space
2020-09-09 – Almost all satellites are powered by solar cells - but solar cells are heavy. While conventional high-performance cells reach up to three watts of electricity per gram, perovskite and organic hybrid cells could provide up to ten times that amount. A research team from the Technical University of Munich (TUM) and the German Aerospace Center (DLR) has now tested this type of cell in space for the first time.
2019-07-09 – With a new spray coating process, very uniform layers of cellulose nanofibers (CNF) can be produced on an industrial scale. X-ray investigations at DESY as well as investigations with an atomic force microscope and neutron scattering at the MLZ, show how the layer is structured and can be tailored for different purposes. A Swedish-German research team led by DESY scientist Adj. Prof. Dr. Stephan Roth presents its structural analyses in the journal Macromolecules .
Vortrag: 60 Jahre Neutronen-Forschung in Garching
2019-01-10 – Forschung mit intensiven Neutronenstrahlen liefert Grundlagenwissen für Physik, Ingenieurwissenschaften und Medizin. Seit mehr als 60 Jahren wird sie auf dem Garchinger Campus der Technischen Universität München (TUM) betrieben. In einem öffentlichen Vortrag gibt Prof. Winfried Petry, ehemaliger Wissenschaftlicher Direktor der Forschungs-Neutronenquelle Heinz Maier-Leibnitz (FRM II), Einblicke in diesen Forschungsbereich.
Neutrons explain higher efficiency of solar cells with additives
2018-11-19 – Organic solar cells are cheaper to produce than conventional photovoltaic systems and can even be sprayed as thin layers on any surfaces. They have been the subject of intensive research since the Nobel price was awarded for conducting polymers in 2000. Physicists at the Technical University of Munich (TUM) have now been able to clarify why additives increase the efficiency of solar cells from a morphological point of view with the use of neutrons at the Heinz Maier-Leibnitz Zentrum (MLZ).
Winfried Petry becomes "Emeritus of Excellence"
2018-10-29 – Prof. i.R. Dr. Winfried Petry has been awarded with the honorary title of Emeritus of Excellence of the Technical University of Munich (TUM). TUM-President Prof. Dr. Dr. h.c. mult. Wolfgang A. Herrmann bestowed the certificate appreciating his academic achievements on 9 October.
Große Instrumente für große Fragestellungen
2018-04-05 – Das Edgar-Lüscher-Seminar für Lehrer der Naturwissenschaften gibt vom Freitag, 27. April, bis Sonntag, 29. April, Einblick in große Forschungsgeräte, wie Röntgen- und Protonenlaser, Neutronenquellen, Neutrinodetektoren und Teilchenbeschleuniger.
Peter Müller-Buschbaum succeeds Winfried Petry
2018-03-29 – The world’s highest-performance neutron source, the research neutron source Heinz Maier-Leibnitz at the Technical University of Munich (TUM), will have a new Scientific Director as of April 1st. With the appointment of Professor Peter Müller-Buschbaum, an internationally renowned researcher has been appointed to succeed Winfried Petry.
Physics Department hosts two conferneces on "soft matter"
2017-11-02 – Two scientific conferences in the area of “soft matter” underline the relevance of interdisciplinary research, that takes place at Technical University of Munich (TUM) in this field. From 9 – 11 October the Physics Department hosted the 48th general meeting of the German “Kolloid-Gesellschaft” (Colloid Society). This was followed by a workshop on fluorescence correlation spectroscopy.
Holiday academy for students
2017-05-03 – “Mountains – Hiking – Learning” is the motto of the “Ferienakademie Sarntal” from 17 to 29 September 2017. Until 9 May, Bachelor and Master students from various disciplines can apply.
X-ray vision reveals how polymer solar cells wear out
2016-10-24 – Scientists from Technical University of Munich have used the accurate x-ray vision provided by DESY’s radiation source PETRA III to observe the degradation of polymer solar cells. Their study suggests an approach for improving the manufacturing process to increase the long-term stability of such organic solar cells.
Edgar-Lüscher-Seminar feiert 40. Jubiläum am Gymnasium Zwiesel
2016-03-18 – Zum 40. Mal findet in diesem Jahr das Edgar-Lüscher-Seminar statt. Zum 40. Mal treffen sich Physiklehrerinnen und Physiklehrer, um spannende Einblicke in das faszinierende Spektrum der modernen Physik zu erhalten.
Nanostructured germanium for portable photovoltaics and battery electrodes
2015-12-07 – Using a new procedure researchers at the Technical University of Munich (TUM) and the Ludwig Maximillians University of Munich (LMU) can now produce extremely thin and robust, yet highly porous semiconductor layers. A very promising material – for small, light-weight, flexible solar cells, for example, or electrodes improving the performance of rechargeable batteries.
