Building on perovskite based tandems some researchers are now exploring perovskite based triple junction solar cells. Our PhD students Mina and Maryam Heydarian gathered a great team of co-authors to summarise the current state of the art. Check it out! pubs.rsc.org/en/Content/Art…

How exciting! Juliane is being recognised for her research by the German Physical Society with the Hertha-Sponer-Price. Congratulations!

It was a pleasure to introduce our research on #perovskite based tandem solar cells in @_electrosuisse' bulletin (in German). Great to see that the electricity industry is interested to learn about the solar cells of the future! bulletin.ch/de/news-detail…

Many Thanks to PV Magazine for picking up our recent research on perovskite-perovskite-silicon triple junctions!

@janosch_go Thank you!

@JBorchertLab Congratulations!

We are delighted to share two recent successes: perovskite-silicon tandems with efficiencies of 30% and perovskite-perovskite-silicon triple junction solar cells with voltages over 2.8V. Both show the huge promise perovskite based multijunction solar cells hold.

The full press news (in English) can be found here: ise.fraunhofer.de/en/press-media…

@pv_tech You unfortunately misread our press news. The tandems (two junctions) have 30%. The triple junctions (three junctions) are not yet as good. The triple junctions have a promising Voc of over 2.8V but currently 20% efficiency.

Fraunhofer ISE develops triple-junction solar cell with conversion efficiency of “over 30%” dlvr.it/SwGXT9

@SolarInMASS The tandems (two junctions) are at 30%. The triple junctions are not as good that. But we are working on it!

Efficiency over 30%

‘triple solar cells consisting of perovskite-perovskite-silicon sub-cells are also promising’

@apfel_lab @FraunhoferISE Dankeschön! 😊

@FraunhoferISE Sehr cool liebe Kolleg*innen

Perowskit-Silicium-Tandemsolarzellen gelten als Hoffnungsträger. Ein Team vom Fraunhofer ISE konnte nun zeigen, dass auch Dreifachsolarzellen bestehend aus Perowskit-Perowskit-Silicium-Teilzellen vielversprechend sind. Neues Paper in ACS Energy Letters: pubs.acs.org/doi/10.1021/ac…

Many thanks to all the co-authors! It was brilliant to work together on this paper. Funding for this research is thanks to projects funded by @HorizonEU and @BMWK. #solarenergy #perovskite #tandem #solarcells #photovoltaics

Perovskite-Silicon tandem solar cells combine two semiconductors for high performance. Can we stack even higher? Absolutely! Check out our new paper. We stacked two different perovskites on top of silicon to achieve a remarkably high voltage of over 2.8V! pubs.acs.org/doi/10.1021/ac…

Only a few more days to apply!

Delighted to see that PV Magazine has picked up one of our recent papers for their reporting. Check-out their write up that explains our research into #perovskite solar cells. The scientific paper is here: sciencedirect.com/science/articl…

Come join us at the University of Freiburg! We are welcoming applications for a technician / engineer to help us keep our solar cell research labs running and constantly improving. Does this sound like you? Check it out: uni-freiburg.de/universitaet/j…

The @GroupHerz at @UniofOxford currently welcomes applications for a 3-year postdoctoral research position on spectroscopy of next-generation semiconductors for light-harvesting applications, through this portal: jobs.ac.uk/job/DBP871/pos…

@sascha_feldmann Congratulations on the cover picture!

for everyone who - like me - had no clue how thick an actual journal issue has become over the years 🤯 a symptom also of publication inflation…(despite growth of research activity overall)?

We are very excited to have our very own contestant in this year's Science Slam Freiburg! First-year PhD student Jann Landgraf will introduce his research combining solar cells and storage devices. Very curious to hear about a wide range of topics! @livMatS_UniFR @UniFreiburg

@AlbrechtLab Oh wow! That is tough. We hope this does not stop your science for too long. Let us know if we can help with anything!

FYI We are not available at the moment!

This week PhD student Maryam Heydarian is representing the group at @nanoGe_Conf's #HOPV23 conference! She will introduce our work on the fabrication and characterisation of perovskite based triple junction solar cells. Check out her poster today! nanoge.org/proceedings/HO…
