Theory meets practice – We’re heading back to HTW Berlin!
The HZB’s BIPV consultancy office (BAIP) is once again coordinating and delivering the lecture series “Building-Integrated Photovoltaics”.
How can solar panels be integrated into architecture in an aesthetically pleasing and efficient way? This is precisely what our colleagues Samira Aden, Thorsten Kühn and Niklas Albinius, together with Rutger Schlatmann, will be demonstrating to Master’s students in Renewable Energy at the Berlin University of Applied Sciences during the coming summer semester.
As a BIPV consulting office, our aim is to break down barriers and disseminate knowledge. For the second time, we are shaping the summer semester with our seminar ‘Building-Integrated Photovoltaics (BIPV)’, enabling us to pass on our practical knowledge to the next generation of aspiring engineers.
Together with the students, we will delve deep into the world of solar building envelopes. In doing so, the students will work on construction project at the HZB and, in parallel with the actual planning, develop their own holistic BIPV concepts in their semester projects – ranging from technical yield simulation and building regulations checks to economic life-cycle analysis.
We are looking forward to a sunny summer semester!
- New method shows how molecular switches are influenced by their neighborsResearchers at Friedrich Schiller University Jena and the Helmholtz Centre Berlin (HZB) have, for the first time, been able to directly observe how the environment surrounding a molecular switch influences its electronic structure. Molecular switches are molecules that can be switched between two states by external influences such as changes in temperature—similar to a switch with the positions »On« and »Off«. Such molecules are being investigated as potential building blocks for future data storage devices or sensor materials. Using magnetic-field-dependent terahertz spectroscopy, the researchers have now, for the first time, been able to distinguish whether neighbouring molecules in a material are in the same or different states. The results have been published in the journal »Angewandte Chemie International Edition«.
- 3D magnetic field experiment at BESSY II takes spintronics a step further(Fe0.63Ni0.3Pd0.07)3P or FNPP is a magnetic material that exhibits complex magnetic structures even at room temperature. This makes the material of interest for spintronics, a field that could enable data processing with significantly lower energy consumption. One potential application is novel magnetic memory devices. However, generating and modifying the desired structures in a controlled manner remains a challenge to date. A new study led by HZB has now taken a step forward in this regard. They demonstrated at the worldwide unique VEKMAG-Station at BESSY II, that a tiny external B-field in the plane of the magnetic patterns is sufficient to change them.
- BESSY II: Evaporated perovskites in tandem solar cells improvedPerovskite-silicon tandem solar cells achieve significantly higher efficiencies than silicon solar cells on their own. One particularly attractive method is co-evaporation of the perovskite precursor molecules on top of the silicon subcell. Scientists at HZB have analysed film growth on the nanoscale at BESSY II and found a new way to improve the quality of the perovskite layer: adding a thin seed layer of caesium chloride between the two sub-cells promotes uniform perovskite growth and suppresses the formation of undesired lead iodide at the interface.
