Helmholtz-Zentrum Berlin für Materialien und Energie GmbH (HZB) is a legally independent member of the Helmholtz Association of German Research Centres, financed by the Federal Government (90%) and the State of Berlin (10%), and has an annual budget of approx. 150 million € with ca. 1,100 employees. HZB also operates BESSY II, which is a third-generation synchrotron radiation source that produces extremely bright X-ray light, and offers access and user support to ca. 3,000 user visits per year.
The mission of HZB focuses on materials research for a sustainable, economic and secure energy supply in the future. The approach includes the understanding of:
HZB’s energy materials research focuses on materials for energy conversion (solar cells) and storage (solar fuels, electrochemical storage), as well as quantum materials (spintronics) that could be of relevance in novel, energy-efficient information technologies. Catalysis materials are also being developed at HZB, for example for artificial photosynthesis and processes for CO2 conversion. Research on energy materials is closely connected with the operation and development of the BESSY II photon source and dedicated unique infrastructures like EMIL, HySPRINT, or the Berlin Joint EPR Lab. The research and development approach focus on thin-film technologies. HZB’s Competence Centre Photovoltaics Berlin (PVcomB) together with HySprint core lab develop photovoltaic technologies and products jointly with industry. It has made significant contributions to the field of photovoltaic module technologies and related production processes and has now extended its contribution to neighboring fields such as Building Integrated Photovoltaics.

We present other two VIPERLAB Research Infrastructures. The first, CHOSE consists of two main infrastructures: the CHOSE@ROME, is located on the campus of the University of Rome Tor Vergata (Italy), and focuses on technological manufacturing processes and device characterization. CHOSE@TURIN, is an infrastructure associated with the University of Turin (Italy) focused on the development of materials. The secon, AIT Viperlab Reseach infrastructures focusses on characterization and reliability tools for the accreditation tests of PV modules, and tools for PV deposition, characterization/reliability and development of thin film coatings.

The stability of perovskite devices is a key point should be addressed to achieve commercialisation. The key factors influencing the stability of the devices are the exposure to oxygen and moisture, UV light, solution processing and thermal effects. Encapsulation and standard testing protocols are required to check and improve stability. The two presented infrastructures offer state of the art equipment for the Perovskite Stability testing of materials and devices.
