HZB is now using green electricity

Since 1 January 2020, HZB is drawing 100 per cent of its electricity from renewable energies. This reduces CO2 emissions by around 17,400 tons per year (related to 2018). By switching to green electricity, HZB acknowledges its responsibility to contribute to climate protection.
HZB decided to switch to green electricity because it has a very high electricity consumption due to the operation of large technical infrastructures. Until now, HZB has been using conventional electricity. In 2018, HZB's demand for electricity and heat caused a total of 20,097 t CO2. By switching to green electricity, 17,424 t CO2 are now avoided.
The new supplier, enercity AG, was selected in a Europe-wide tender. The electricity provider will supply exclusively green electricity, which must be verified by certificates approved by the Federal Environment Agency's register of proof of origin. These certificates confirm the ecological origin of the electricity. It is expected that the electricity will be generated from hydropower in Scandinavia.
- Perovskite solar cells: New Young Investigator Group funded by BMBF at HZBIn the COMET-PV project, Dr Artem Musiienko aims to significantly accelerate the development of perovskite solar cells. He is using robotics and AI to analyse the many variations in the material composition of tin-based perovskites. The physicist will set up a Young Investigator Group at HZB. He will also have an affiliation with Humboldt University in Berlin, where he will gain teaching experience in preparation for a future professorship.
- Strategisches Positionspapier zur Stärkung der SolarindustrieFrankfurt, 06. März 2025 – Die führenden deutschen Solarforschungseinrichtungen, die Fachabteilung „Photovoltaik Produktionsmittel“ des Industrieverbands VDMA und das Produktionsplanungs-Unternehmen RCT Solutions, haben ein gemeinsames Positionspapier zur Stärkung der deutschen und europäischen Solarindustrie veröffentlicht. Dieses wird nun an die Parteien übermittelt, die nach der Bundestagswahl im Bundestag vertreten sind. Ziel ist es, die vorgeschlagenen Maßnahmen in die Koalitionsverhandlungen einzubringen und damit die Grundlage für eine widerstandsfähige und wettbewerbsfähige Solarindustrie in Deutschland zu schaffen.
- Innovative battery electrode made from tin foamMetal-based electrodes in lithium-ion batteries promise significantly higher capacities than conventional graphite electrodes. Unfortunately, they degrade due to mechanical stress during charging and discharging cycles. A team at HZB has now shown that a highly porous tin foam is much better at absorbing mechanical stress during charging cycles. This makes tin foam an interesting material for lithium batteries.
