Together with @uni-freiburg.de and KAUST we showed that surface passivation of perovskite top cells is possible in solar cell tandems with today's industry standard for solar cells.

Ein internationales Forschungsteam der #UniFreiburg, @fraunhoferise.bsky.social und KAUST zeigt: Eine gezielte Molekülbehandlung steigert Wirkungsgrad von Perowskit-Silizium- #Tandemsolarzellen auf 33,1 Prozent. uni-freiburg.link/tandemsolarz... @pv-physicist.bsky.social @stefanglunz.bsky.social

Great cooperation between the Albert-Ludwigs-Universität Freiburg @uni-freiburg.de,
KAUST (King Abdullah University of Science and Technology), and Fraunhofer-Institut für Solare Energiesysteme ISE @fraunhoferise.bsky.social !

In our new paper in Science Magazine, we demonstrate that a surface layer can be used not only to passivate surfaces but also to enhance the properties of the bulk of #perovskite solar cells.

Scratching the surface is not enough!

This should be a guiding principle of good science - and politics 😉 .

But it also applies to #photovoltaics!

#Hydrogen: The Two-Faced Element in Crystalline #Silicon for #Solar #Cells!

In our new article, Benjamin Hammann explains how hydrogen contributes to the passivation of defects at interfaces, but it can also bring some unpleasant surprises, such as #LeTID degradation.

Our last #WeekendRead recommendation of the year is on perovskite silicon solar cells and how to achieve "nice" #perovskite absorbers.
This approach is of relevance for the industrialization of tandem solar cells.

6 Fraunhofer institutes joined forces to identify the most sustainable paths for the market launch of #perovskite silicon tandem solar cells.

Tired of measuring your #solar cells and modules with an old-fashioned filter wheel or monochromator? Then take a look at David's article on how to use an LED-based solar simulator to get the job done quickly and over a large area! #photovoltaics

🏠 Custom-colored modules increase the #acceptance of #photovoltaics on #buildings, a joint study with the University of Freiburg finds. Particularily on historic buildings, colored modules increase the social acceptance to the same level as on modern buildings. www.ise.fraunhofer.de/en/press-med...
