Climate change and its causes are undisputed. But how do we get from knowledge to action? What can science contribute to this? On Thursday, 5.12.2019 at 17:00 Clara Mayer (Fridays for Future), Volker Quaschning (HTW Berlin and Scientists for Future), Bernd Rech (scientific director of the HZB) and Kira Vinke (Potsdam Institute for Climate Impact Research) will discuss these questions. The event takes place in the Bunsen lecture hall of WISTA in Adlershof and is open to the public. Admission is free.
Countless scientific studies show how important it is to limit global warming. We must reduce greenhouse gas emissions at all levels of society and in all sectors in order to achieve our climate targets. But there are many hurdles to implementation. What can science do to speed up action here? Should science interfere at all?
These questions are discussed in an open debate. Participants are Clara Mayer from Fridays for Future, Prof. Volker Quaschning (HTW Berlin and Scientists for Future), Prof. Bernd Rech (Scientific Director of the HZB) and Dr. Kira Vinke of the Potsdam Institute for Climate Impact Research. The debate will be moderated by Rutger Schlatmann (Head of PVcomB at HZB).
The debate is open to the public and will take place in the Bunsen lecture hall of WISTA. Admission is free.
As the discussion takes place within the international user meeting at the HZB, the discussion language is English.
Venue: Bunsen Lecture Hall WISTA, Rudower Chaussee 17, 12489 Berlin
Time: Thursday, 5.12.2019 from 17:00 until 18:30
- CIGS-perovskite tandem cell achieves record efficiency of 25.5 %A Berlin-based team from HZB and Center for the Science of Materials Berlin (CSMB) at the Humboldt-Universität zu Berlin has set a new record for a tandem solar cell. Using a combination of a CIGS semiconductor layer and perovskite, along with several optimised intermediate layers, they were able to convert 25.5% of sunlight into electrical energy. The previous record for this combination of materials and this size of cell stood at 24.6%. The new record has been certified and is visible in the prestigious Solar Cell Efficiency Tables (the "Green Tables"), which serve as the definitive ledger for the global photovoltaic community.
- Disorder creates new properties in compound semiconductorsAn international research team has demonstrated that the intrinsic disorder of the compound semiconductor CuInSnS₄ can be exploited to influence its optical properties. While the atomic vibrations also sense the local disorder, their response is averaged over many different local environments and therefore appear isotropic, as expected for a cubic crystal. In contrast, the optical excitations, known as excitons, are much more sensitive to the local arrangement of atoms. Surprisingly, they show a direction-dependent optical response even though the average crystal structure is cubic. These findings shed new light on the relationship between disorder and material properties, opening up new options for targeted 'disorder engineering' in optoelectronic and photocatalytic devices.
- Perovskite solar cells: Predictions of long-term stabilityReliable statements about the long-term stability of perovskite solar cells are still difficult to make. However, a new study by Dr Carolin Ulbrich’s team, published in the renowned journal Joule, highlights which methods are useful for this purpose and identifies areas where further research is needed.
