One of the main advantages here is that this can be applied to almost any surface because of how thin it is.

From the article:

We can envisage perovskite coatings being applied to broader types of surfaces to generate cheap solar power, such as the roofs of cars and buildings and even the backs of mobile phones. If more solar energy can be generated in this way, we can foresee less need in the longer term to use silicon panels or build more and more solar farms.

Concrete is also used in buildings and other facilities like pumped storage hydropower.

Yeah it's in the description

Of silicon panels.
In the lab, mixing silicon and perovskites has already achieved 34%.

It's more about the use of perovskite (while retaining durability), which should lower the cost of the panels.
The efficiency improvement is a bonus.

BlurBusters have nice articles about this.

TL;DR: Less motion blur and less artifacts (like stroboscopic effects, which can also be visible at 480hz).

And in general I didn't expect to see praise for a group that has "A Curse Upon the Jews" as part of their official slogan.

I personally ended up getting the Glove80.
I don't have experience with the Advantage 360, but there are some reviews of people who have used both and compared them.
Like this and this.

There's also the Svalboard, although it might be a step too far for you. It has options for integrated trackballs / trackpoints.

Just chiming in about Tailscale.
