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.

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.

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 !

Electron accumulation across the perovskite layer enhances tandem solar cells with textured silicon Reducing charge carrier transport losses, improving selectivity, and minimizing non-radiative recombination are essential for enhancing the efficiency and stability of perovskite/silicon tandem solar ...

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.

Featured Publications Q3-2024 - Fraunhofer ISE Here we present our highlight articles.

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.

Measuring the External Quantum Efficiency of Tandem Photovoltaic Modules Using an LED‐Based Solar Simulator A novel procedure enabling the measurement of tandem external quantum efficiency using light-emitting diode-based solar simulators is presented. The accuracy of the procedure is first evaluated based...

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...
