I'll comment maybe just on the first story.

I think this is neither earth shattering nor boring.

It's somewhere solidly in between.

This is a paper published in Jack's Journal of American Chemical Society.

And 130% quantum yields isn't as earth shattering as it sounds either.

It just means that there are 1.3 singlets generated from a single photon.

Normally, you'd have one.

So it's not like earth shattering.

It's an incremental advance in

in the chemistry.

I think this is actually liquid phase chemistry, which means it isn't immediately practical for solid photovoltaics.

Moderately interesting, but the field is filled, the solar photovoltaic field is filled with moderately interesting advances that cumulatively eventually generate something interesting.

But I would say, first story, moderately interesting slash incremental.

Have you been tracking perovskite progress?

Yeah, I mean, so perovskites are sort of the white knight for the solar PV space.

Historically, they haven't been that stable.

They're a pain to work with.

On the other hand, instability issues are being very aggressively resolved because their quantum efficiency is higher than silicon.

So I don't speak for the solar PV industry, but if I did, I'd probably say there's a broad expectation that

Eventually, there will probably be some sort of broad shift to perovskites as they get more and more stable, maybe.
