Step one here?

Yep.

And then as we move over here it actually gets set free next step in the process i like this machine this machine is nice and shiny it's nice shiny in the new it's very cool so this is where after we do all the coatings in there we finish the stack by putting an electrode on top so we've got to be able to make an external connection and so that's what this system is for this is sputtering system which will allow us to put down a thin layer of silver or a thin layer of ito ito indium tin oxide is a transparent conductive oxide It's used if you want to be able to see through your material, but still have electricity pulled out of it.

So things like your phone screens are going to have ITO on it.

Things like solar cells are going to have ITO.

Very useful material, but does require some very specialized equipment in order to deposit.

So the perovskite is absorbing the light, and that is creating the electricity.

What is this machine actually testing for? What kind of diagnosis is?
