    World record again at HZB: Almost 30 % efficiency for next-generation tandem solar cells
    Three HZB teams led by Prof. Christiane Becker, Prof. Bernd Stannowski and Prof. Steve Albrecht have jointly managed to increase the efficiency of perovskite silicon tandem solar cells fabricated completely at HZB to a new record value of 29.80 %. The value has now been officially certified and is documented in the NREL-charts. This brings the 30 percent mark within reach.

    From niche to mainstream: the keys to making BIPV happen today | pv magazine webinar
    Building-integrated photovoltaics (BIPV) are a symbiosis between clean energy generation and design that could turn future buildings into generation hubs, and creating new revenue streams, while helping cover our net-zero emissions targets.

    This pv magazine Webinar will investigate how BIPV companies and stakeholders such as architects, the construction sector, smart city initiatives and regulations, and more, can work together, to create generating assets from large buildings in urban environments and commercial applications, to residential environments.

    Many colleagues are currently working in their home offices, exchanging information by telephone or video conferencing. Nevertheless, we all miss the opportunity to meet other colleagues in the hallway or in the kitchen. That's why we are shifting "kitchen conversations" to the digital. Today we introduce Samira Aden. She is an architect and works in the Consulting office for building-integrated Photovoltaics(BAIP) at HZB.

    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.
