Out now in @ACS_AMI, @_hcon’s work links PA “SAM” deposition method to layer coverage and device performance using:
1. ITO etching
2. Dip coating
3. Secondary diphosphonic acid molecule (after first PACz)
Also found Pb adsorption varies w PA treatment!

Excited to share our work on understanding diamines' surface reaction mechanism to optimize Si–perovskite tandems! Huge thanks to @SnaithGroup for hosting me & @_hcon, and to all the incredible collaborators @joelalexsmith @CUBoulderCHEM @BaenaLab et al.➡️ pubs.acs.org/doi/10.1021/acs…

Congrats to @margheritaddei,@SnaithGroup,@CUBoulderCHEM and all co-authors on this collaborative effort! Diamines react at the surface with formamidinium, forming a new cyclic molecule that boost Si–perovskite tandem performance!

Gillian's @acsnano paper presents the use of 2PACz interface modifiers to significantly enhance the brightness of perov quantum dot LEDs. They show suppressed efficiency roll-off at high levels of current & brightness, outperforming traditional HTLs!

Fascinating lab tour @gingerlabUW @UW on how to convince #perovskites and beyond to reveal their secrets to advanced atomic force microscopy.
Thanks @_hcon et al. for showing us around during the lunch break of @IEEEPVSC.

So grateful for the opportunity to collaborate with the exceptional @SnaithGroup on Si-perovskite tandem solar cells! 🤝 Thanks to @joelalexsmith and whole team for the incredible hospitality! Thrilled about the scientific achievements of these 6 weeks and exciting next steps☀️♻️ – at Oxford, England

EDA additive for PL homogeneity, phase stability and higher performance in FACs 1.7eV perovskites is out in @ACSEnergyLett pubs.acs.org/doi/abs/10.1021… Incredible teamwork @gingerlabUW, @SnaithGroup,SethMarder.Special thanks @joelalexsmith being the best mentor even across the ocean.

SO AS I WAS SAYING IT'S CALLED THE NREL CHART. IT PLOTS THE RECORD EFFICIENCIES OF DIFFERENT SOLAR TECHNOLOGIES OVER TIME. PEROVSKITES AND ORGANICS ARE IMPROVING MUCH MORE QUICKLY THAN SILICON DID AS YOU CAN SEE ON THE BOTTOM RIGHT OF THE CHA..

Had a great time sharing our group's latest research at the Unconventional Semiconductors GRC. Great to see current and former members of @gingerlabUW.

Cornell students Pamela Wildstein and Christopher Galantino sat down with @CornellCALS Prof. @amchatrchyan for a press conference @COP25CL. They shared Cornell's public engagement mission and lessons learned from developing a #ClimateChange education program. @engagedcornell

Update: 2 players were removed from the team today.
Nobody was told their removal was based on this article, but I am sad.
Sad, bc as someone who works daily to inspire female athletes, I never want anyone to feel the way these players feel.
Whoa. 👀
