The BAIP consulting office for building-integrated photovoltaics has been launched as a knowledge transfer project in 2019, funded by the Helmholtz Association's Initiative and Networking Fund. In order to build a bridge between the world of construction and photovoltaics, the consulting office provides comprehensive knowledge for architects, planners, builder-owners, investors and urban developers. After an excellent evaluation, the BAIP consulting office will be permanently financed by HZB.
Classic rooftop photovoltaics are not suitable for every building. But there are now many more options for generating solar power where it is needed: Photovoltaic modules can be integrated into façades and other parts of the building envelope, and they are available in different colours and surface structures, thus also enabling aesthetic designs. However, these new solutions are not yet sufficiently known among experts in the world of construction.
In order to close this knowledge gap, Björn Rau and Markus Sauerborn founded the consulting office in 2019 as a knowledge transfer project and obtained funding from the Helmholtz Association's Initiative and Networking Fund. The BAIP office informs and advises stakeholders from the construction industry nationwide on the possible applications of building-integrated photovoltaics (BIPV) - and does so neutrally and independently of products. BAIP offers consultations and very quickly designed concrete training formats in cooperation with the chambers of architects in Germany and several universities. After being evaluated as excellent by the Helmholtz Association, the HZB is now anchoring the BAIP consulting office as a long-term institution in the field of solar energy and is taking over the permanent basic funding.
The BAIP advice centre is headed by Björn Rau and currently employs Samira Aden and Thorsten Kühn, two proven experts from the field of architecture, who design and implement the consultations and training formats for various specialist audiences.
- Perovskite triple-junction solar cells: Even more efficient with GO/SAM bilayersPerovskite semiconductors efficiently convert sunlight into electrical energy; they are also inexpensive and extremely lightweight. A team at HZB has developed a triple-junction solar cell comprising different perovskite semiconductors, with a novel bilayer of graphene oxide (GO) and a self-assembled monolayer (SAM) as the hole conductor. This bilayer significantly increases both efficiency and long-term stability. The efficiency of the novel perovskite triple-junction solar cell is 27.3% and shows hardly any decline even after more than 770 hours of operation. The study has been published in the renowned journal Joule.
- Green Deal Ukraїna at the Ukraine Recovery ConferenceEnd of June, the Ukraine Recovery Conference (UCR2026) took place in Gdańsk, Poland. Unlike previous editions, URC2026 introduced a dedicated Energy Platform, jointly organised by the Ministry of Energy of Ukraine and the Ministry of Climate and Environment of Poland, which brought together energy-related discussions, announcements, and side events in one place, increasing the visibility and coordination of key energy topics. Green Deal Ukraїna, an initiative coordinated by HZB, organised three events on the sidelines of URC on research and energy topics as part of the conference.
