Perovskite

So to increase the chances of that happening, the silicon layer has to be made quite thick.

Now for reasons of physics, which again we won't delve into here, perovskites don't need that extra phonon to get their electrons moving, which means they can be manufactured as very thin films.

Perovskites can also be chemically manipulated or tuned to capture different wavelengths of light to silicon, which means they can be adapted for a wide range of different light sources, and they can be applied as a thin layer on top of silicon wafers, creating so-called tandem or multi-junction cells.

The resulting cell can then absorb a far wider spectrum of light while maintaining a good working voltage and in theory overcoming that Shockley-Keizer limit of roughly 30% efficiency.

That revelation started a whole field of tandem research that's still going on today.

and how you guys are creating an ink that can be printed on top of and use alongside in tandem with silicon solar panels.

So I think just to start us off here, maybe Blake, you can start by just explaining what Perovskite actually is and we'll dig into the technology and into the business.

Yeah, absolutely.

So perovskites is essentially just a name for a class of materials.

It does a good job of coagulating a lot of this data and publishing it available for everyone.

So a lot of solar technologies have come and gone.

Perovskite is the one that has lasted because of the demonstration of its performance and ability for solar applications.

And to get into what Sofab Inks is developing, literally an ink that can be printed onto materials that now make them able to generate electricity through solar
