    Invitation to HySPRINT – Industry Day “New Frontiers in PV Research: Emerging Perovskite Semiconductors”

    On 13 October, Helmholtz-Zentrum Berlin will be hosting its first Industry Day on the topic of Perovskite Solar Cells. Following a recap of the current state of research and development and the future potential of perovskite solar cells, participants from industry will be able to give a brief presentation to show their company’s interest in the field. Intensive discussions during the Industry Day will be the starting point for future cooperation. [...].

    The miracle material graphene: convex as a chesterfield

    Graphene possesses extreme properties and can be utilised in many ways. Even the spins of graphene can be controlled through use of a trick. This had already been demonstrated by a HZB team some time ago: the physicists applied a layer of graphene onto a nickel substrate and introduced atoms of gold in between (intercalation). The scientists now show why this has such a dramatic influence on the spins in a paper published in 2D Materials. As a result, graphene can also be considered as a material for future information technologies that are based on processing spins as units of information.

    Breakthrough at EMIL: First undulator radiation in the CAT experiment

    When the EMIL laboratory (Energy-Materials In-Situ Laboratory Berlin) was ceremoniously inaugurated a year ago in the presence of Federal Minister for Research Johanna Wanka, it was a major milestone for energy materials research at HZB. Ever since, HZB has been building the system that will bring X-ray beams all the way from BESSY II to the EMIL apparatuses. Until the BESSY light is fully available, the scientists have been working with X-rays from a conventional laboratory source. Now, the beamline operators have succeeded in guiding the X-rays from Undulator UE48 in the BESSY II experimental hall to the CAT experiment in the EMIL laboratory. There, it was quantitatively measured using a focus measuring chamber. [...].

    Solar hydrogen production by artificial leafs:

    Scientists analysed how a special treatment improves cheap metal oxide photoelectrodes

    Metal oxides are promising candidates for cheap and stable photoelectrodes for solar water splitting, producing hydrogen with sunlight. Unfortunately, metal oxides are not highly efficient in this job. A known remedy is a treatment with heat and hydrogen. An international collaboration has now discovered why this treatment works so well, paving the way to more efficient and cheap devices for solar hydrogen production. [...].
