- Berlin Energy Days: Integrated photovoltaics - active areas for the energy transitionThe energy transition needs photovoltaics, and photovoltaics need space. There are large areas that have hardly been used so far: For example, solar cells can be integrated into the shell of buildings and vehicles, or installed in traffic routes, over farmland and flooded opencast mines. On Wednesday, 28 April 2021, experts from the HZB consulting office for builiding integrated PV (BAIP) and other research institutions will present these options. The event will take place as part of the Berlin Energy Days, and participation is free of charge after registration.
- Solar cells: Losses made visible on the nanoscaleSolar cells made of crystalline silicon achieve peak efficiencies, especially in combination with selective contacts made of amorphous silicon (a-Si:H). However, their efficiency is limited by losses in these contact layers. Now, for the first time, a team at Helmholtz-Zentrum Berlin (HZB) and the University of Utah, USA, has experimentally shown how such contact layers generate loss currents on the nanometre scale and what their physical origin is. Using a conductive atomic force microscope, they scanned the solar cell surfaces in ultra-high vacuum and detected tiny, nanometre-sized channels for the detrimental dark currents, which are due to disorder in the a-Si:H layer.
- Instrument at BESSY II shows how light activates MoS2 layers to become catalystsThin films of molybdenum and sulfur belong to a class of materials that can be considered for use as photocatalysts. Inexpensive catalysts such as these are needed to produce hydrogen as a fuel using solar energy. However, they are still not very efficient as catalysts. A new instrument at the Helmholtz-Berlin Zentrum’s BESSY II now shows how a light pulse alters the surface properties of the thin film and activates the material as a catalyst.
- Accelerator physics: Experiment reveals new options for synchrotron light sourcesAn international team has shown through a sensational experiment how diverse the possibilities for employing synchrotron light sources are.

The German federal government's National Hydrogen Strategy clearly identifies the great need for research in this area, which will be the foundation for breakthroughs and leaps in innovation. The Helmholtz-Zentrum Berlin (HZB) and two Max Planck institutes – the Fritz Haber Institute (FHI) and the Max Planck Institute for Chemical Energy Conversion (MPI CEC) – are pooling their expertise for this purpose and together with Humboldt Universität zu Berlin they are jointly establishing the CatLab research platform in Berlin. CatLab is intended as a bridge between pure research and industry, and is being funded by the German Federal Ministry of Education and Research (BMBF) with more than 50 million euros. In total, the five-year development project will cost about 100 million euros.
- Perovskite Solar Cells: paving the way for rational ink design for industrial-scale manufacturingFor the production of high-quality metal-halide perovskite thin-films for large area photovoltaic modules often optimized inks are used which contain a mixture of solvents. An HZB team at BESSY II has now analysed the crystallisation processes within such mixtures.

- Silicon-perovskite tandem solar cells: New facilities pave the way for industrial-scale production
Perovskites are regarded as promising materials for solar cells, able to be manufactured at low cost while at the same time being extremely efficient. They are particularly suitable for tandem solar cells that combine a cell made of silicon and one of perovskite. As a result, sunlight is more completely used when generating electrical energy. So far, the advantages of such cells have only been available for use at small laboratory scale. With two new, highly innovative production facilities, researchers at the Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) are now creating the basis for future production on an industrial scale.
- Upconversion of photons at low light intensities – the key to new applications in energy and bioengineeringThe region of the spectrum that can be utilised for producing electrical energy can be considerably extended by converting low-energy (longer wavelength) photons into high-energy (shorter wavelength) photons. But so far, this has only been possible at high intensities of light. Now for the first time, scientists from the Helmholtz-Zentrum Berlin (HZB) and the Federal Institute for Materials Research and Testing (BAM) have been able to produce a usable effect from relatively weak light by combining certain nanoparticles with what is known as a meta-surface. This paves the way for future applications in photovoltaics, for the detection of biological substances, and for electrical-field sensors.

- On the road to non-toxic and stable perovskite solar cellsThe promising halide perovskite materials for solar energy conversion show high efficiencies, but this comes at a cost: The best perovskite materials incorporate toxic lead which poses a hazard to the environment. To replace lead by less toxic elements is not easy since lead-free perovskites show lower stability and poor efficiencies. Now, an international collaboration has engineered a new hybrid perovskite material with promising efficiency and stability.

- Reaching climate targets with building integrated PhotovoltaicsBy 2050, the building stock in Germany must be almost climate-neutral in order to achieve the climate targets - an ambitious goal. Especially in cities with multi-storey buildings, roof areas alone do not offer sufficient space to cover a significant portion of the electricity demand with photovoltaics. There is now a wide range of façade elements that generate photovoltaic electricity. So far, however, such building-integrated PV modules have rarely been installed. The Advisory Centre for Building Integrated Photovoltaics (BAIP) at HZB wants to change this:
