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.

International Research Team Unlocks the Power of Passivation for Perovskite Silicon Tandem Solar Cells - Fraunhofer ISE
An international research team of photovoltaics scientists demonstrated that passivation of the perovskite top cell is possible in combination with textured silicon bottom 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.
