Excited to share the first paper of my postdoc @NREL published now in @acsnano!! #perovskite #quantumDot solar cells have terrific voltages, and we now know a bit more why they’re so good & what’s still limiting them. My first twitter 🧵 (1/7)

Great work by Jonas on the pathway to 30% #perovskite solar cells.
Oh my God that took forever but it is finally out!
Congratulations to Jonas for being so persistent.

The ultimate tool to track the Covid-19 pandemic, which could be an inspiration for using open-data and smart online tools in materials science. A logarithmic scale and normalisation of data may often suffice to gain (first) significant insights

X-ray absorption spectroscopy with a time-resolution of some tens of miliseconds allows to follow the nucleation and growth of nanocrystal in real time - although this meant pushing the SuperXAS beamline @psich_en to its limits !

[Shalini Singh @Shalini_UL]

Our in situ XAS and SAXS study revealing the nucleation and growth kinetics of quaternary nanocrystals is finally out in @acsnano

Happy to share this collaborative work between @WeizmannScience @lunduniversity @HagesLab @LabUnold @HZBde @UFLChE on the Synthesis-Characterization-Modeling of Energy Transport in CsPbBr3 #Perovskite Nanowires.

Good morning everybody! We are glad to be part of this work lead by @AmranLux @EikeKoehnen and @AlbrechtLab. The good news is that there seems to be a decent room for further improvement! 👏

[Steve Albrecht's Lab @AlbrechtLab]

Out in @ScienceMagazine: We combined interface passivation with fast charge extraction for stable, >29%-efficient record perovskite/silicon tandem solar cells. Big collaboration for which we are very grateful. Congrats @AmranLux, @EikeKoehnen!

Check out Hampus's in-situ GIWAXS work on combinatorial injekt printed inorganic perovskites @HZBde! 🟡🟠🟤🔴⚫️

[Pepe Marquez @PepeMarquez9]

Hampus's first paper is out #openaccess in @JMaterChem.

We looked at the phase transitions in the CsPb(I,Br)3 solid solution in a single heating/cooldown in a combinatorial sample. High-throughput with a liquid metal jet source!😱

check out this new publication on some quite unusual properties of the p-type transparent conductor CuI

[Andrea Crovetto @and_crovetto]

Usually moisture makes everything worse but here is an exception. In CuI p-type transparent conductors, a well-chosen humidity level actually improves their conductivity! Published in @ACS_AMI with @LabUnold https://t.co/WYwHzJgQ9Y

First group meeting with @FatimaAkhundova as a new member! 👏👏

[Pepe Marquez @PepeMarquez9]

Check out our latest paper #OA @NatureComms on high-efficiency CIGSe from #ZSW!

Plenty of fun stuff in this project led by Max Krause and Daniel Abou-Ras.

I hope you all are having a lovely summer! We haven't been very active lately, but we are slowly getting back.

Check out our thoughts in this comment on measuring spatial profiles of trapped charges in perovskite solar cells with @KirchartzThomas.
