Accolade and social commitment at the same time: Prof. Dr. Bernd Rech has become a new member of acatech
The German “National Academy of Science and Engineering – acatech” has admitted Prof. Dr. Bernd Rech, an expert in renewable energies, into its circle of members. Bernd Rech has headed the Institute of Silicon Photovoltaics at Helmholtz-Zentrum Berlin (HZB) since 2006 and has been the acting Scientific Director of HZB since May 2017. For many years, and in many capacities, he has been a champion for knowledge transfer. “This appointment is an accolade for his scientific accomplishment, and at the same time involves an honorary mandate,” acatech writes in its press release. The federal- and state-funded academy advises social and political actors on technological matters.
“As a member of acatech, I will weigh in more strongly on debates regarding the issue of our energy supply. Within the academy, I am part of an interdisciplinary team with diverse areas of expertise, which develops recommendations for action for politics and society. It is an exciting and very important set of duties, to which I am very much looking forward,” Bernd Rech says.
Bernd Rech is an internationally renowned expert above all in the fields of photovoltaics and thin-film technology, and has distinguished himself through many successes in technology transfer. He has published more than 300 papers and holds more than ten patents. Rech has also been actively involved for many years in promoting the networking of energy research in Germany. He has been the spokesperson for the “Renewable Energies” research program of the Helmholtz Association since 2008. He is also on the board of the Energy Working Group of the Deutsche Physikalische Gesellschaft. This affords him a complete picture of the scientific and technological challenges involved in converting to a low-carbon energy supply of the future.
acatech welcomes 26 new members
A total of 26 scientists have been newly accepted into acatech. The members of acatech are from the engineering and natural sciences, the humanities, economics and the social sciences, and operate at the interface between science, economics and politics. In interdisciplinary projects, they collaborate with experts from industry and society to develop options and recommendations for action. Subject matters of these projects range from the global energy supply to digitalisation, Industry 4.0 and telecommunications. More information
- An elegant method for the detection of single spins using photovoltageDiamonds with certain optically active defects can be used as highly sensitive sensors or qubits for quantum computers, where the quantum information is stored in the electron spin state of these colour centres. However, the spin states have to be read out optically, which is often experimentally complex. Now, a team at HZB has developed an elegant method using a photo voltage to detect the individual and local spin states of these defects. This could lead to a much more compact design of quantum sensors.
- Solar cells on moon glass for a future base on the moonFuture settlements on the moon will need energy, which could be supplied by photovoltaics. However, launching material into space is expensive – transporting one kilogram to the moon costs one million euros. But there are also resources on the moon that can be used. A research team led by Dr. Felix Lang of the University of Potsdam and Dr. Stefan Linke of the Technical University of Berlin have now produced the required glass from ‘moon dust’ (regolith) and coated it with perovskite. This could save up to 99 percent of the weight needed to produce PV modules on the moon. The team tested the radiation tolerance of the solar cells at the proton accelerator of the HZB.
- Optical innovations for solar modules - which are the most promising?In 2023, photovoltaic systems generated more than 5% of the world’s electrical energy and the installed capacity doubles every two to three years. Optical technologies can further increase the efficiency of solar modules and open up new applications, such as coloured solar modules for facades. Now, 27 experts provide a comprehensive overview of the state of research and assess the most promising innovations. The report, which is also of interest to stakeholders in funding and science management, was coordinated by HZB scientists Prof. Christiane Becker and Dr. Klaus Jäger.
