Thrilling to see our paper out now! The work was carried by the vigor of our many colleagues, many many thanks. Exciting to experience how perovskites can be a mighty boost for solar energy and I hope its market rise continues to exceed expectations.
Some key messages below:
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!

Thank you for the interview and nice article!

Mixed monolayers have potential for hole-selective layers with a tailored fit on the specific absorber layer. Hope this is useful for labs with wetting issues, it greatly improved our lab workflow at #HySPRINT.
A quick fix for wetting issues with some organic monolayers! Adding di-phosphonic acid improves processing yield while keeping same perovskite solar cell performance.
Fast publication by @LtMagomedov and @AmranLux in @ACSEnergyLett.

We are back!
Our Perovskite/Silicon Tandem Solar Cells entered the @NREL chart with a certified efficiency of 32.5%
Thanks to all the amazing people contributing to this achievement.

Congratulations to Doro @doromenzel! She received the best presentation award at the MRS Fall Meeting #f22mrs in Boston with her talk about field effect passivation induced by LiF at the Pero/C60 interface. For more insight see onlinelibrary.wiley.com/doi/…

Congratulations to @JWillis__ and @doromenzel for the best presentation awards at the EQ05 symposium on #Contacts and #Interfaces for #Optoelectronics #F22MRS @Materials_MRS! Great job! And thanks to our sponsor @VONARDENNE 👏

Big congratulations to @EikeKoehnen for receiving the Tiburtius prize for his dissertation @TUBerlin @HZBde !
His endurance in perovskite tandem cell optimization has led to a few world records and big steps in our groups' processing power.

Wide-bandgap perovskite solar cells with an optimized recipe for scalable slot-die coating. We have also demonstrated tandem solar cells with them and industry-compatible Si bottom cells. Out in @ACSEnergyLett.
Big congrats to Ke Xu!

Wäre das Wachstum der #photovoltaik in Deutschland so weitergegangen wie 2004 bis 2010 (p=48,15%), und nicht durch @fdp @cdu ausgebremst worden, hätten wir heute 827 GW PV installiert, die ca. 800 TWh/a Strom produzieren würden (80 #Atomkraftwerke), d.h. 100% Strom + 24% vom Gas!
ALT Jährlicher Zubau der Photovoltaikleistung in Deutschland (in GW/a) 2002 bis 2022: Gutes Wachstum bis 2010, danach ca. 6 verlorene Jahre.

Im IPCC-Bericht wird deutlich: Wir können die schlimmsten Auswirkungen der Klimakrise noch abwenden. Es ist theoretisch sogar noch möglich (aber unwahrscheinlich) die Erderhitzung auf 1,5 Grad zu beschränken. Die größte Sensation des Berichts aber ist eine andere... 💌1/13
We could finally shed some (near-UV) light on the LiF effect.
#HySPRINT
Still curios about why there are some differing effects in some laboratories, and why Voc is only enhanced when LiF and C60 are evaporated within the same vacuum run.
Curious why LiF interlayer increases open-circuit voltage in PSCs? Find out why it is field effect passivation, similar to Si solar cells:

I am thanking the whole #HySPRINT lab, Prof. Bernd Rech and @AlbrechtLab for this. Unfortunately, there aren't many prices for whole teams, but maybe in future 🙂

Happy #EarthDay2022 - new episode up about the big brain banking move of financing fossil fuel expansion while claiming to be climate friendly while citing a source that actually says to do the opposite of what you’re doing. Or just watch these 3 seconds. youtu.be/NJ7W6HFHPYs

here is a quick thread for anybody who didn't read the 3 ipcc reports published in the last year (hello, politics, business and news editors) summarizing what hundreds of the world's top scientists concluded in their mega-review of the academic literature on climate change 1/
Glad to have helped in this study. Interestingly, N2 plasma was needed to activate the oxide for good functionalization by a self-assembled monolayer. This has increased stability and voltage of the top cell.
A Nature research paper reports an organic/perovskite hybrid tandem solar cell with a high open circuit voltage, enabled by a thin metal oxide interconnect layer go.nature.com/3uFWjVZ

Fantastic responses to some pretty shocking "interviewing" 👏

Eine ausgewogene Berichterstattung ist immer wichtig? Nicht, wenn es um Fakten geht.
ALT Dachzeile: Fakten vs. Meinung. Headline: Das steckt hinter False Balance. Darunter ist eine Waage zu sehen. Auf der linken Seite: viele rote Männchen, auf der rechten Seite ein dunkelblaues Männchen. Daneben ist ein Fernseher mit einem roten und einem dunkelblauen Männchen. Darunter ist wieder eine Waage. Diesmal mit je einem roten und dunkelblauen Männchen auf jeder Seite. Die Waage ist ausgeglichen.
One step closer from lab to fab.
#renewableenergy
In collaboration with Q CELLS we have shown that industrial, cost-efficient silicon solar cells are viable for tandems with 28.7% efficiency.
Congrats to Kári Sveinbjörnsson @SveKari and Bor Li for their diligent processing! @HZBde #HySPRINT
