    Reaching climate targets with building integrated Photovoltaics
    By 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:

    World record for tandem perovskite-CIGS solar cell
    A team headed by Prof. Steve Albrecht from the HZB will present a new world-record tandem solar cell at EU PVSEC, the world's largest international photovoltaic and solar energy conference and exhibition, in Marseille, France on September 11, 2019. This tandem solar cell combines the semiconducting materials perovskite and CIGS and achieves a certified efficiency of 23.26 per cent. One reason for this success lies in the cell’s intermediate layer of organic molecules: they self-organise to cover even rough semiconductor surfaces. Two patents have been filed for these layers.

    Photovoltaics are growing faster than expected in the global energy system
    Dramatic cost reductions and the rapid expansion of production capacities make photovoltaics one of the most attractive technologies for a global energy turnaround. Not only the electricity sector, but also transport, heating, industry and chemical processes will in future be supplied primarily by solar power, because it is already the cheapest form of electricity generation in large parts of the world. This is where opportunities and challenges lie - at the level of the energy system as well as for research and industry. Leading international photovoltaic researchers from the Global Alliance for Solar Energy Research Institutes describe the cornerstones of future developments in an article published in the journal "Science" on 31 May.

    Towards the Climate Neutral City: Independent consulting office for integrating photovoltaics into buildings
    The Helmholtz-Zentrum Berlin is opening a national consulting office for integrating photovoltaics into buildings (BAIP) this spring. The consulting office will support building owners, architects, and municipal planners in activating building envelopes for power generation. The project is being funded by the Helmholtz Association over a period of four years as part of its knowledge transfer programme.
