Attn: all journal editors Subject: high efficiency halide perovskite devices will not boost citations? Glad to see the data suggest scientists pay attention to the quality of science. https://t.co/sG5GMnPGe6
pubs.rsc.org
One of the most common metrics of success for a perovskite solar cell is the device efficiency. Other metrics, like long-term stability and price, are also vital for commercialisation, but it is the...

Another stream of consciousness thought. Get AI to generate a list of prior references that should have been cited (we all miss some of the 30,000 out there). This would even be helpful to the authors.

(2/2) the authors can revise based on reviews or receive an * for unreconciled, peer review agreed upon concerns/complaints. After 1 year the period ends. This seems particularly important for accelerating the fidelity of AI training.

(1/2) Here’s an idea that needs consideration and refining, particularly for perovskites. All manuscripts accepted after peer review have a grace period of 1 year where researchers can submit legitimate concerns, that themselves get peer reviewed or sent straight to the authors.

Is it a thing now that journal editorial staff will make edits to figures before publishing online and without telling the authors about the revisions? This has happened twice recently that I know of.

A very nice collaboration led to this follow up work on photoinduced halide perovskite/organic HTM interfacial reactions that is now out in #JACS! Iodine species doping and moving in and out of the HTM are the origin of many observables good and bad. https://t.co/7m2FoKzYH0

Metal halide perovskites are promising for optoelectronic device applications; however, their poor stability under solar illumination remains a primary concern. While the intrinsic photostability of...

A little insight from @NREL ‘s @RossKerner @KellySchutt, Kai Zhu on “PbI2 Reagent Impurities Catalyze Mixed-Cation Halide Perovskite Ink Degradation” | ACS Energy Letters
pubs.acs.org
Non-negligible K, acetate (OAc–), and nitrate (NO3–) impurities have been identified in commercially available PbI2 reagents, plausibly remnant from synthesis. Here, we characterize the individual...

Halide ion migration in Mixed-Halide Perovskite Devices -Barry Rand, @joe_jberry &cowks use elemental mapping to measure halide redistribution in mixed-halide perovskite solar cells with quasi-ion-impermeable contact layers under different bias polarities
pubs.acs.org
Voltage-induced halide segregation greatly limits the optoelectronic applications of mixed-halide perovskite devices, but a mechanistic explanation behind this phenomenon remains unclear. In this...

Some of our @NREL work digging into a few details of halide perovskite reagent impurities and purification is finally out! Special thanks to @GilesEperon @FeiZhang_TJU @SevNHabis @JonahMessinger
pubs.acs.org
Mirroring established semiconductor technologies, using higher quality reagents to synthesize halide perovskite materials results in improved optoelectronic performance. In this study, we selected...

Congrats to Zhaojian! We’re walking the walk of our Joule perspective on halide segregation in perovskites. @joe_jberry

In this study, three voltage thresholds are observed, corresponding to 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamino)-9,9′-spirobifluorene (spiro‑MeOTAD) doping, reversible halide segregation, and...

Looks like the inverse Occam’s razor opinion article had an almost immediate impact!

Nature Nanotechnology - We will now explicitly ask reviewers to flag up to us and authors whether a simpler model or theory could explain the experimental data in a given manuscript.

We've finally proven a low temperature degradation pathway to metallic Pb in perovskites facilitated by amines!
pubs.acs.org
The degradation of alkylammonium PbII halide perovskites, in the dark and upon irradiation near room temperature, involves coordinated amine as the dominant reducing agent to yield Pb0 near room...

How important is the fact that ions diffuse out of #perovskite? In https://t.co/vZlwAqJAyl
@bitton_sapir’s modeling shows that it may mask all in-perovskite ion motion effects. It may also change it into N or P type.
pubs.rsc.org
Theoretical studies of ion migration have thus far focused on migration within the perovskite layer only. This reflected a “hidden” assumption that the electron/hole blocking layers also function as...

The Complicated Morality of Named Inventions Viewpoint by @brunoehrler @emhutter1 @joe_jberry discuss why "the energy science community should consider refraining from using “Shockley-Queisser limit” and instead use terms like “detailed-balance limit” https://t.co/XgnyFYdFkW

I'm filled with gratitude for my coauthors who helped finish our latest publication quantifying permeation rates of iodine through HTMs used in perovskite devices! Check it out! https://t.co/m55nwdUspa

Iodine-containing volatiles are major degradation products of halide perovskite materials under irradiation, yet iodine diffusion kinetics into and throughout organic hole transport materials (HTMs)...
