The Supervisory Board of tesa SE has appointed Dr. Ingrid Sebald to the Executive Board. In her new role at the international manufacturer of innovative adhesive tapes and self-adhesive product solutions, she will be responsible for technology and sustainability. "With Ingrid Sebald, we have an excellent leader who has been instrumental in shaping our global business through innovation and technology with great success," says Dr. Norman Goldberg, CEO of tesa SE. According to a company statement, the newly created board role responsible for technology and sustainability underscores the importance of these topics: "Technology and sustainability are closely linked, and this new Executive Board position emphasises tesa’s commitment to developing and promoting more sustainable adhesive solutions." Frank Kolmorgen, member of the tesa SE Executive Board (Industry) since July 2022, resigned at the beginning of the year in agreement with the Supervisory Board.
Dr. Ingrid Sebald has been responsible for technology at tesa since January 2023 and additionally for sustainability since April 2024. She holds a doctorate degree in chemistry and has been with tesa since 2021. Prior to her current role, she was Head of Product Development in the Business Unit Automotive. She began her career at Huhtamaki Films, where she held various management positions in sales, research and development. Before joining tesa, she was responsible for R&D, marketing and sales at Infiana and marketing and technology at Loparex. Both companies are manufacturers of specialty films and release liners.
As tesa also announced, Arunjai Mittal was elected as the new Chairman of the Supervisory Board of tesa SE at an extraordinary meeting. He succeeds Dr. Martin Stark, who has resigned from his position for personal reasons. Arunjai Mittal has been a member of the Supervisory Board since 2014.

Solar energy expansion
is picking up speed
The expansion of photovoltaics is currently exceeding the German government’s targets. This is according to the German Institute for Economic Research (DIW Berlin), which also points out the challenges involved, such as the need for integration into the electricity system and dependence on China.
Just under 91 gigawatts are currently installed, compared with the target of 88 gigawatts for the whole of 2024. Rooftop installations are the main driver. Although the number of ground-mounted PV systems is also growing, there is still plenty of potential for further expansion in this segment. "The German government should consider once again increasing the tender volumes in the ground-mounted segment. This could also help to keep expansion costs down, as groundmounted systems are cheaper," says s tudy author F elix Schmidt. As PV grows, so do the challenges for the electricity system. In parallel with the expansion, the prices achievable on the wholesale market have fallen. "One challenge is to efficiently integrate the highly variable amounts of solar power into the electricity market over the course of the day and the year. Better price incentives are needed to ensure that storage systems are operated in a way that benefits the system," explains co-author Alexander Roth.
Microdisplays achieve
45% transparency
As part of the HOT ("High-performance transparent and flexible micro-electronics for photonic and optical applications") project by the Fraunhofer IPMS, OLED microdisplays with 20% transparency were developed. The technology has now been advanced further, and for the first time, 45% transparency has been achieved in CMOS OLED microdisplay.
The technology uses silicon backplane that contains the entire active matrix drive electronics for the pixels. An organic frontplane is monolithically integrated on the topmost metallisation layer, which simultaneously serves as the drive contact for the organic light emitting diode. The second connection of the OLED is formed by a semi-transparent top electrode shared by all pixels, resulting in themselves not being transparent.
Researchers from the Fraunhofer Institute
for Photonic Microsystems IPMS have
significantly increased the transparency of
OLED microdisplays.
