Perovskite solar cells: Defects trap charge carriers - and release them again An international team at HZB and Charles University Prague has investigated how charge carriers in so called MAPI-perovskite semiconductors interact with different defects. Their results help to improve perovskite solar cells.
HZB uses electricity-producing facade wall as real laboratory In the presence of the State Secretary for Economic Affairs, Energy and Operations of the State of Berlin, Christian Rickerts, the HZB officially commissioned the solar façade of a new research building on 6 September 2021. What makes it so special is ...
Perovskite solar cells: Interfacial loss mechanisms revealed Metal-organic perovskite materials promise low-cost and high-performance solar cells. Now a group at HZB managed to de-couple the different effects of self-assembled monolayers of organic molecules (SAMs) that reduce losses at the interfaces.
Green hydrogen: Why do certain catalysts improve in operation? Now a HZB-team headed by Marcel Risch has observed at BESSY II how two simultaneous mechanisms are responsible for this. The catalytic activity of the individual catalysis centres decreases, but the morphology of the catalyst layer also changes.
VIPERLAB: EU project aims to boost perovskite solar industry in Europe HZB is coordinating a major European collaborative project to open up new opportunities for the European solar industry. The VIPERLAB project involves 15 renowned research institutions from Europe, as well as Switzerland and Great Britain.
Perovskite/silicon tandem solar cells on the threshold of 30% efficiency The tandem cell provided stable performance for 300 hours – even without encapsulation. To accomplish this, the group headed by Prof. Steve Albrecht investigated physical processes at the interfaces to improve the transport of the charge carriers.
Best electrolyser/photovoltaics combinations demonstrated in test fields One of the most promising ways to increase the availability of solar energy is to convert excess production into hydrogen. The PECSYS project has investigated the best possible material and technology combinations to facilitate such an operation.
Seminar für Architekt*innen Bauwerkintegrierte Photovoltaik: Architektur –... Im September veranstaltet die Beratungsstelle für BIPV „BAIP“ zusammen mit der Architektenkammer Niedersachsen ein Seminar für Architekt*innen zum Thema Bauwerkintegrierte Photovoltaik: Architektur-Gestaltung und Ausführung
On the road to non-toxic and stable perovskite solar cells To replace lead by less toxic elements is not easy since lead-free perovskites show lower stability and poor efficiencies. Now, an international collaboration has engineered a new hybrid perovskite material with promising efficiency and stability.
