Workshops at the Scienteens Lab

On campus Limpertsberg, the Scienteens Lab offers three different workshops in physics:

1. High-tech research for better solar cells: Does the sun also shine in our labs?

How does a solar cell work? How can you measure its efficiency with a sun simulator? During this physics workshop, students get the opportunity to discover the answers to these exciting questions.
They get a better understanding of the current research on solar cells and find out why different solar
cell technologies exist.

During the workshop, the students learn through hands-on experiments how to:

  • Produce a dye-sensitized solar cell
  • Test the short-circuit current and the open circuit voltage
  • Measure the conversion efficiency of different solar cells with a sun simulator
  • Calibrate the light intensity and investigate the influence of the temperature with scientific equipment.
  • Use different lasers to learn about the reciprocity relation of an LED and a solar cell and predict the emission colour of an LED only from its absorption properties

At the end of the day, the results of all the groups are discussed, and the participants discover which group created the best DIY solar cell.








2. Modern spectroscopy in the field of materials research: How does sunscreen protect our skin?

Why do we need sunscreen? How and why does it work? In order to answer those questions, learn more about light sources, modern spectroscopy, wavelength and particle properties of light.

During this physics workshop, students get the opportunity to synthesise their own sunscreen and to test its effectiveness. Different experimental tools are applied to understand the sunscreen:

  • diffraction grating to analyse light and familiarise with the wave properties of light
  • a self-made spectroscope to characterise light sources and get a better understanding of light-matter interaction
  • a spectrometer to measure how effective the sunscreen is

At the end of the day, the groups assemble their results from the research experiments and draw a conclusion.








3. Mayonnaise, a culinary star on the test bench - a liquid or a solid?

During this physics workshop, students get the opportunity to analyse the behaviour of a specific
material in all its forms and learn to establish a relation between its structure and its flow behaviour.

Different experimental tools are applied to analyse the mayonnaise:

  • Microscopy to investigate the structure
  • Rheometer and Hagen-Poiseuille equation to study the flow properties

At the end of the day, each group presents its results and conclusions.









Practical information for all the physics workshops

At the end of a workshop, each student receives a certificate attesting to his participation.


The main languages used during physics workshops are German, Luxembourgish and English. Special arrangements are possible for workshops in French.

Time schedule

The workshops take place from 9:00h till 15:30h with a lunch break of one hour. During the lunch break the students can use the canteen. The lunch schedule need to be observed, so that the afternoon activities can resume on time. Please note, that the participants might want to bring a small snack for the morning, as the lunch break can be a bit late


The physics workshops take place at the Physics and Materials Science Research Unit of the University of Luxembourg on Campus Limpertsberg.
Information on how to access Campus Limpertsberg is available here and the map below shows the Science Building.

By Bus, from the central train station / Luxembourg-city:
Take line 2 (Limpertsberg / L.T. Michel Lucius - Gasperich - Kohlenberg / Boy Konen) or line 4 (Limpertsberg / LT Michel Lucius - Leudelange, Gemeng), stop at "Lycée Technique Michel Lucius", and walk down rue Guillaume Capus.
