@AntonioAbate83 @NatureEnergyJnl @HZBde @miliba01 @jpcorreabaena @EPFL_en a substantial recovery effect for short timescales but on the long timescales used for the MPP tracking in this paper essentially not. Yet we observe these large ionic losses and they do not recover. Therefore, they govern the degradation. Let's collaborate on the next work!

@AntonioAbate83 @NatureEnergyJnl @HZBde @miliba01 @jpcorreabaena @EPFL_en Hi Antonio, sorry that we forgot to cite your pioneering work on the recovery, which we like a lot. However, this is a complex topic that is difficult to cover with sufficient detail in our paper. We are working actively to address this in a follow-up work. We also observe ...

Martin Stolterfoht and team show that internal electric field screening induced by ion migration is a dominant contributor to the initial performance loss of #perovskite #SolarCells. buff.ly/3Uc2FI4

@AlbrechtLab @Jarla_T @picaprioglio @JonathanWarby @DrFLang @neher_labs @SnaithGroup @Artanoon Thank you for the amazing teamwork! I am very curious to see how these losses will be considered for analyzing and improving the stability of perovskite cells in the future!! nature.com/articles/s4156… @CUHKofficial #SPP2196 @unipotsdam @Uni_Wuppertal

Why are ionic losses important for intrinsic perovskite solar cell degradation? @Jarla_T wrote a great publication to answer this question: nature.com/articles/s4156… @picaprioglio @JonathanWarby @DrFLang @neher_labs @SnaithGroup @Artanoon

So happy that this is finally out!! And super grateful to all the amazing coauthors for their contribution, and of course @Stolterlab for directing this huge work!

A study from @mor_schmidt, @Stolterlab @unipotsdam, @brunoehrler @_amolf uses simulations & transient capacitance measurements to explore ion migration in perovskite photovoltaics, showing that device properties significantly impact capacitance transients journals.aps.org/prxenergy/abst…

All-perovskite tandems with certified 27.5% efficiency: PI surface treatment of 1.8eV perovskite reduces deep trap state density, improves carrier lifetime and enables 1.36V Voc. Thanks to all coauthors! @Stolterlab @SnaithGroup @Uni_Wuppertal @HZBde doi.org/10.1002/adma.2…

Also explore fellowship opportunities with us! We are looking for highly motivated candidates with exceptional and diverse backgrounds for next-generation solar cell research! gs.cuhk.edu.hk/admissions/sch… If this looks interesting to you, pls contact me :) mstolterfoht@ee.cuhk.edu.hk

Dear fellow researchers, I am excited to announce that I have joined the Electronic Engineering Department at The Chinese University of Hong Kong (CUHK)! Our lab will now be active in both Hong Kong and Potsdam. @CUHKofficial

Researchers from @stolterlab demonstrate the impact of ionic losses in perovskite solar cells and analyse methods to quantify the ion density. BACE and low-frequency Mott-Schottky can be combined to asses the ion density over a wide range. go.acs.org/5jK

The fundamental investigations on recombination losses of the Sn-Pb perovskite is still a cornerstone for highly efficient solar cells even though we already achieved proud progress. @AlbrechtLab @SnaithGroup @Stolterlab @WileyGlobal onlinelibrary.wiley.com/doi/full/10.10…

@pero_pal @VMLC_PV @univgroningen 😥

Since I moved to 🇩🇪 everytime I have to claim money for a conference it makes me really miss 🇳🇱 @univgroningen 😭 German paperwork will be the end of me, such a waste of time, and you have to print everything which is sad in 2022...

Our latest paper on subcell-selective analysis of all-perovskite tandem solar cells, supervised by the amazing @DrFLang, is finally out! Read about efficient tandems (25.9% stabilised!), lossless interconnects and targeted subcell optimisation: onlinelibrary.wiley.com/doi/10.1002/ae…
