Unfortunately, the operational stability was reduced, which we provide preliminary investigations of, and discuss potential avenues for improvement. It’s critical to bring light to these issues!

More interestingly, the surface passivations homogenized the surface, This enabled 60cm2 spin coated perovskite-silicon tandem solar cells with certified PCE of 28.9%! Likely there are better options for scalability, but I never believed this level would be possible with spin-coated absorbers.

We find PCl has a surface dipole that helps align the bands of the C60 and perovskite and induces a field effect passivation. Combining both passivations lead to certified Vocs >2V and the stack actually improves the PLQY, making this a passivating contact.

In this system, we find that pfbpa can chemically passivate surface defects, increasing the plqy of bare films. There may also be losses that come from new states arising from the interface of two materials, and other losses coming from poor band alignment of the perovskite and fullerene absorbers.

There is more than one kind of interfacial loss. One is surface defects that come from, for example, surface defects coming from unsatisfied bonds at the surface.

The core of the paper is the investigation of perfluorobenzenylphosphonic acid (pfbpa) and piperazinium chloride (PCl) as surface passivation molecules in perovskite solar cells.

That’s my girl!!! Always so proud of you ♥️

Really cool work! Congratulations 🎉

Looking forward to reading it when it’s out 😉

Congratulations for making it through the marathon review process! Great work!

Perovsky is such a good tag, will be using this from now on!

Congratulations Daryl! I’m looking forward to seeing it out in the wild 😁
