    Nanodiamonds can be activated as photocatalysts with sunlight
    Nanodiamond materials have potential as low-cost photocatalysts. But until now, such carbon nanoparticles required high-energy UV light to become active. The DIACAT consortium has therefore produced and analysed variations of nanodiamond materials. The work shows: If the surface of the nanoparticles is occupied by sufficient hydrogen atoms, even the weaker energy of blue sunlight is sufficient for excitation. Future photocatalysts based on nanodiamonds might be able to convert CO2 or N2 into hydrocarbons or ammonia with sunlight.

    How photoelectrodes change in contact with water
    Photoelectrodes based on BiVO4 are considered top candidates for solar hydrogen production. But what exactly happens when they come into contact with water molecules? A study in the Journal of the American Chemical Society has now partially answered this crucial question:  Excess electrons from dopants or defects aid the dissociation of water which in turn stabilizes so-called polarons at the surface. This is shown by data from experiments conducted at the Advanced Light Source at Lawrence Berkeley National Laboratory. These insights might foster a knowledge-based design of better photoanodes for green hydrogen production.

    Green hydrogen: faster progress with modern X-ray sources
    In order to produce green hydrogen, water can be split up via electrocatalysis, powered by renewable sources such as sun or wind. A review article in the journal Angewandte Chemie Int. Ed. shows how modern X-ray sources such as BESSY II can advance the development of suitable electrocatalysts. In particular, X-ray absorption spectroscopy can be used to determine the active states of catalytically active materials for the oxygen evolution reaction. This is an important contribution to developing efficient catalysts from inexpensive and widely available elements.

    Green hydrogen: Why do certain catalysts improve in operation?
    Crystalline cobalt arsenide is a catalyst that generates oxygen during electrolytic water splitting in the production of hydrogen. The material is considered to be a model system for an important group of catalysts whose performance increases under certain conditions in the course of electrolysis. Now a HZB-team headed by Marcel Risch has observed at BESSY II how two simultaneous mechanisms are responsible for this. The catalytic activity of the individual catalysis centres decreases in the course of electrolysis, but at the same time the morphology of the catalyst layer also changes. Under favourable conditions, considerably more catalysis centres come into contact with the electrolyte as a result, so that the overall performance of the catalyst increases.

    Solar hydrogen for Antarctica - study shows advantages of thermally coupled approach
    A team from the Helmholtz-Zentrum Berlin, Ulm University, and Heidelberg University has now investigated how hydrogen can be produced at the South Pole using sunlight, and which method is the most promising. Their conclusion: in extremely cold regions, it can be considerably more efficient to attach the PV modules directly to the electrolyser, i.e. to thermally couple them. This is because the waste heat from the PV modules increases the efficiency of electrolysis in this environment. The results of this study, which has now been published in Energy & Environmental Science, are also relevant for other cold regions on Earth, such as Alaska, Canada, and high mountain regions, for example. In these places, solar hydrogen could replace fossil fuels such as oil and petrol.

    Green hydrogen: "Rust" as a photoanode and its limits
    Metal oxides such as rust are intriguing photoelectrode materials for the production of green hydrogen with sunlight. They are cheap and abundant, but in spite of decades of research, progress has been limited. A team at HZB, together with partners from Ben Gurion University and the Technion, Israel, has now analysed the optoelectronic properties of rust (haematite) and other metal oxides in unprecedented detail. Their results show that the maximum achievable efficiency of haematite electrodes is significantly lower than previously assumed. The study demonstrates ways to assess new photoelectrode materials more realistically.

    Photoanodes made of metal oxides are considered to be a viable solution for the production of hydrogen with sunlight. α-SnWO4 has optimal electronic properties for photoelectrochemical water splitting with sunlight, but corrodes easily. Protective layers of nickel oxide prevent corrosion, but reduce the photovoltage and limit the efficiency. Now a team at HZB has investigated at BESSY II what happens at the interface between the photoanode and the protective layer. Combined with theoretical methods, the measurement data reveal the presence of an oxide layer that impairs the efficiency of the photoanode.

    The sun shines at the South Pole as well – and in summer almost around the clock. Instead of supplying research stations in the Antarctic with crude oil for producing the electricity and heating they need, solar hydrogen could be produced from sunlight in summer as an alternative. Hydrogen has a high energy density, is easy to store, and can be used as fuel when needed later without polluting the environment. An intriguingly simple idea - but one that raises many questions. Matthias May (HZB) and Kira Rehfeld (Heidelberg University) now want to examine how feasible this kind of solar fuel generation might be in Antarctica.

    If CO2 emissions do not fall fast enough, then CO2 will have to be removed from the atmosphere in the future to limit global warming. Not only could planting new forests and biomass contribute to this, but new technologies for artificial photosynthesis as well.

    Finding and understanding low cost catalysts: it all comes down to the iron
    A team has investigated more than one hundred iron-nickel catalysts containing various admixtures of chromium. At BESSY II, they also analysed the configurations of the electrons in the individual elements. The team showed that an increasing proportion of chromium primarily influences the energy levels of the iron electrons, which are important for the catalytic effect. The results of this high-throughput study will assist the knowledge-based search for better specific catalysts.

    Research for Germany’s energy transition: EMIL@BESSY II approved for the Kopernikus “Power-to-X” project
    The storage of excess solar and wind power is one of the greatest challenges in Germany’s energy transition. To address this, the German Federal Ministry for Education and Research (BMBF) has created the “Power-to-X” (P2X) project under its Kopernikus programme. P2X will advance research into converting electrical energy from the sun and wind into basic chemical compounds, gaseous energy media, and fuels. A total of 17 research institutions, 26 industrial enterprises, as well as three non-governmental organisations are involved, and the BMBF is funding the first development phase of the project at a level of 30 million Euros. The Helmholtz-Zentrum Berlin will participate in the planned research, using the advanced synthesis capabilities and the BESSY II synchrotron-based X-ray characterization tools at the recently inaugurated EMIL@BESSY II laboratory complex.

    Riddle of missing efficiency in zinc oxide-based dye-sensitised solar cells solved.
    To convert solar energy into electricity or solar fuels, you need specialised systems of materials such as those consisting of organic and inorganic thin films. Processes at the junction of these films play a decisive role in converting the solar energy. Now a team at HZB headed by Prof. Emad Aziz has used ultra-short laser pulses and observed for the first time directly how boundary states form between the organic dye molecules and a zinc-oxide semiconductor layer, temporarily trapping the charge carriers. This explains why zinc-oxide (ZnO) dye-sensitised solar cells have not yet met expectations. The results evolved from collaboration between Monash University (Australia) and Joint Lab partners Helmholtz Zentrum Berlin (HZB) and the Freie Universität Berlin (FU Berlin). They have now been published online by Nature in the open access magazine Scientific Reports.

    Solar fuels:a refined protective layer for the “artificial leaf”
    A team at the HZB Institute for Solar Fuels has developed a process for providing sensitive semiconductors for solar water splitting (“artificial leaves”) with an organic, transparent protective layer. The extremely thin protective layer made of carbon chains is stable, conductive, and covered with catalysing nanoparticles of metal oxides. These accelerate the splitting of water when irradiated by light. The team was able to produce a hybrid silicon-based photoanode structure that evolves oxygen at current densities above 15 mA/cm2. The results have now been published in Advanced Energy Materials.

    Distinguished Lectures at HZB: Prof. T. Krauss will talk about Photovoltaics and Photonic nanostructures
    Solar power has the highest potential among all renewable energy sources, it is clean and practically inexhaustible. Despite the already very high performance of silicon solar cells with 25% efficiency and low costs, a lot of research is yet required in order to realise the vision of a solar-powered society. Can we reduce module cost by integrating solar cells into buildings? Can we improve efficiency without increasing cost, by adding low-cost materials such as perovskites? What role can photonic nanostructures play to help control the flow of light?

From 11 to 16 May 2014, the participants of the WE Heraeus seminar concentrated intensively on the topic of “converting sunlight to hydrogen” and discussed new materials and processes for photovoltaic and (photo)catalytic applications.
    Matthias May impressively demonstrated on his poster how water acts on differently prepared surfaces of III-V compound semiconductors and what interactions occur. It is highly important to study this effect in detail because the initial reaction with water is critical in the development of suitable materials and processes for solar fuels. May prepared two different surfaces of gallium and indium phosphide and then analyzed and compared the influence of water using photoelectron spectroscopy and in-situ reflection anisotropy spectroscopy.

    The best of two worlds: Solar hydrogen production breakthrough
    Using a simple solar cell and a photo anode made of a metal oxide, HZB and  TU Delft scientists have successfully stored nearly five percent of solar energy chemically in the form of hydrogen. This is a major feat as the design of the solar cell is much simpler than that of the high-efficiency triple-junction cells based on amorphous silicon or expensive III-V semiconductors that are traditionally used for this purpose. The photo anode, which is made from the metal oxide bismuth vanadate (BiVO4) to which a small amount of tungsten atoms was added, was sprayed onto a piece of conducting glass and coated with an inexpensive cobalt phosphate catalyst. “Basically, we combined the best of both worlds,” explains Prof. Dr. Roel van de Krol, head of the HZB Institute for Solar Fuels: “We start with a chemically stable, low cost metal oxide, add a really good but simple silicon-based thin film solar cell, and – voilà – we’ve just created a cost-effective, highly stable, and highly efficient solar fuel device.”
