New cookbook "Science-Food" - download now!
For this cookbook, staff and guest researchers have told us their favorite dishes from their home countries.
People from many different countries work at the Helmholtz-Zentrum Berlin and enrich our atmosphere. For our cookbook, employees and guest researchers from six continents have contributed their favorite recipes.
Home-cooked dishes are a great way to raise a smile. Hospitality is an important part of the tradition in most countries of the world. Eating, talking and laughing together unites people from all nations. In this new edition of the cookbook, you will find a unique collection of international dishes: from Korean appetizers to Mexican main courses and French desserts.
Let yourself be inspired by the culinary journey around the globe.

- New contact material boosts the efficiency of perovskite solar cellsA newly developed material for the electron contact improves the efficiency of single perovskite solar cells and perovskite/silicon tandem solar cells. The new material is based on a carborane molecule. It offers several advantages over the standard material C60, as shown by the study led by Steve Albrecht’s team. The new material has since been patented and is already commercially available.
- From Colombia to Berlin: Finding My Way in a New WorldIt was almost 11 p.m. when I arrived in Berlin. After a long journey from Colombia, all I wanted was to get to my accommodation, take a shower, and finally sleep.
Instead, I missed my train. Thinking it would follow the same route as the previous one as it would in my hometown of Medellín I confidently boarded the next train. About twenty minutes later, I realized something was wrong. I was heading in the wrong direction.
As if that was not enough, my phone battery was almost empty. Suddenly, I found myself alone in a city I had never visited before, late at night, speaking a language I did not understand, with no idea how to get back.
This was not how I had imagined the beginning of my first international trip....
- Precision interface chemistry pushes perovskite solar cells beyond 26% efficiencyAn international research collaboration has developed a new molecular strategy for controlling one of the most critical interfaces in perovskite solar cells. The resulting solar cells reached a power conversion efficiency of 26.19% in the n i p architecture, together with strong operational stability under prolonged illumination and elevated temperature. The results have been published in the Journal of the American Chemical Society.
