2023

By 2023, billions of Internet of Things (IoT) devices found their way into almost every area of life, industry and critical infrastructures. As these permanently connected smart devices process very sensitive data, their up-to-dateness is essential to close vulnerabilities and thus enhance cybersecurity – especially in times of hacker attacks, data misuse or industrial espionage. In this context, a new Fraunhofer ISI study analysed data of 52 billion devices, their geographical location – and whether their installed firmware is up-to-date and which impact the European General Data Protection Regulation has on this. The findings show that it is only a matter of time before very serious cyberattacks could easily happen.

A new Fraunhofer ISI Lithium-Ion battery roadmap focuses on the scaling activities of the battery industry until 2030 and considers the technological options, approaches and solutions in the areas of materials, cells, production, systems and recycling. The study examines three trends in particular: The production of performance-optimized, low-cost and sustainable batteries.

SThe Fraunhofer Institute for Microstructure of Materials and Systems IMWS is working with partners to develop a marketable, completely bio-based and non-toxic plasticizer for use in elastomers and thermoplastics. Using rapeseed oil as a starting product, more sustainable solutions for tires and packaging should become possible. The project partners also want to design a corresponding pilot plant in central Germany as part of the "Biocerine" project.

Within the Research Project “PV-MoVe”, researchers at the Fraunhofer Institute for Energy Economics and Energy System Technologies IEE investigated how to use active switching loss reduction networks for power semi-conductors to enable smaller, more lightweight, and more cost-efficient photovoltaic converters. Using newly developed additional circuitry, switching frequencies for a 50 kW PV inverter could be increased by a factor of 2.5 – 3 for the DC input stage and by a factor of 10 – 12.5 for the inverter output stage. The project was worked on in cooperation with project part-ners Infineon Technologies AG and SUMIDA Components & Modules GmbH from 2019 to 2023, funded by the German Federal Ministry of Economic Affairs and Climate Action BMWK.

Stefan Lange from the Fraunhofer Centre for Silicon Photovoltaics CSP in Halle (Saale) has been awarded the Heinz Bethge Prize for Materials Science, worth 500 euros, by the Heinz Bethge Foundation for Applied Electron Microscopy for his dissertation entitled "Parasitic oxides at buried interfaces in modern silicon solar cells". His findings can contribute to a better understanding of the fundamental properties of the layer systems in a solar cell and the associated electronic properties.

Bremerhaven, November 10, 2023 – Senator Kristina Vogt and Lord Mayor of Bremerhaven Melf Grantz are launching trial operation at the Hydrogen Lab Bremerhaven (HLB) together with the Fraunhofer Institute for Wind Energy Systems IWES. The infrastructure is thus now ready for the research work in Bremerhaven focusing on the in-teraction between wind turbines and electrolytic hydrogen produc-tion to begin. The HLB received a total of €16 million in funding from the European Regional Development Fund (ERDF) and the State of Bremen.

The quality and manufacturing of the encapsulation and backsheet films play an important role in the reliability of a solar module. Only if the quality, processing and compatibility of the films are right, protection of the interconnected solar cells against environmental influences can be guaranteed and the module be ready for use for decades. Together with partners, the Fraunhofer Center for Silicon Photovoltaics CSP is investigating new types of encapsulation and backsheet films for PV modules that should have a service life of at least 40 years.

A cross-organizational team from Rigaku SE and Fraunhofer IISB has established a new semicon-ductor material characterization method in their jointly operated Center of Expertise for X-ray Topography in Erlangen, Germany. They succeeded not only in developing an industry-ready X-ray topography system, but also in employing defect detection and quantification algorithms, achieving a worldwide unique material characterization method for silicon carbide (SiC) wafers. SiC is an excellent semiconductor for application areas like electric mobility and transportation, sustainable energy supply, industrial infrastructure up to sensors and quantum technologies even under harsh operating conditions. As representatives for the whole research team, Dr. Kranert and Dr. Reimann from Fraunhofer IISB and Dr. Hippler, Managing Director Rigaku Europe SE, have won the Georg Waeber Innovation Award 2023 from the Förderkreis für die Mikroelektronik e.V. (Microelectronics Promotion Society).

Led by Fraunhofer ISI, the BOLD project provided scientific support accompanying three field trials and twelve other research projects on electric trucks powered by overhead lines. Together with ifeu and Öko-Institut and funded by the German Federal Ministry for Economic Affairs and Climate Action, Fraunhofer ISI analyzed the acceptance of the technology, the opportunities and barriers in industry and the policy landscape as well as the climate and environmental impact of the technology. The now published final report describes the main lessons from these projects and assesses the potential rollout of the technology.

Existing strategies to reduce carbon dioxide emissions are unlikely to be sufficient to mitigate climate change. One way to reduce the amount of carbon dioxide (CO2) in the air is through negative emissions, which is the removal of CO2 from the air followed by storage. Various natural and technical processes are available for this purpose. One of these technical options is Direct Air Capture and Carbon Storage (DACCS).
