Excited to share the recent publication of our work using dual-variational autoencoders (dual-VAEs) for geometrical determination of anisotropic nanostructures! pubs.acs.org/doi/10.1021/acs…
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 new study in @J_A_C_S on aminosilane surface passivation in halide perovskites.
We find optimizing deposition conditions is key for maximizing passivation w/o harming performance & aminosilanes chemically react with FA+
Great collab!

Our team is searching for a Director of Education and Workforce Development who demonstrates a passion and commitment to science education and outreach, while also contributing to all of IMOD's Integrative Activities programming. Apply by 10/22 at lnkd.in/g9eDG7qR
Out now in @J_A_C_S , we develop straightforward platform for quantifying charge localization in molecularly doped conjugated polymers. Congrats to @WeiYouResearch and all co-authors on this collaborative effort!

In our latest @JACS, led by @rjewestbrook in collab w Toney (@CUBoulder), Jen (@CityUHongKong), & Brédas (@uarizona) groups, we demonstrate the link between solid-state packing, exciton recombination, and device performance in state-of-the-art OPVs doi.org/10.1021/jacs.5c08244 🧵
Further consideration of solid-state packing in novel donors and acceptors should enable OPVs above 20% in the near future.
Thanks to who made this possible: Andrew Levin, Wei Gao, Urvashi Bothra @urvashi_bothra, Saied Md Pratik @saiedmdpratik, Baobing Fan, Francis Lin, Qian-Qian Zhang @barbaragoco, Khoa Ngo, Werner Kaminsky, Jean-Luc Brédas, Veaceslav Coropceanu, Alex Jen, & Michael Toney, @UW_CEI.
We use time-resolved electrostatic force microscopy to map how surface potential evolves in perovskites during photoexcitation. We show nanoscale variations in recombination dynamics as affected by morphology and passivation! @rajgiri @acsnano 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!

New paper using a convolutional neural network to improve parameter extraction & data reconstruction for time-resolved EFM! trEFM helps us measure electronic & ionic dynamics in semiconductors; our CNN obtains more accurate parameters for these dynamics

It was an honor to visit UW (Clean Energy Institute) in Seattle. Beautiful campus. Wonderful colleagues.
Thanks for hospitality to: @EdenTz_chem , @velianlab , Daniel Gamelin, Brandi Cossairt, David Ginger @gingerlabUW and their students, @UW_CEI
Was a pleasure having @mvkovalenko as our @UW_CEI seminar speaker today. Thank you for a great talk detailing your extensive work innovating QD synthesis and design!

(1/2) Check out our latest @natcomm demonstrating the role of aggregates in donor polymers for OPVs showing tailored aggregation leads to high PLQYs (~26%) & exciton delocalization. This knowledge will aid the progression of OPVs towards 20% efficiency.
