Ultra thin, light weight, more eco friendly than silicon cells ?

Now are we going to expect gold to rise in price?

Yes, by exactly 0.44 cents per gram to keep the cost of electricity balanced.

link  to the material in question:
https://news.stanford.edu/2021/12/14/new-materials-deliver-ultrathin-solar-panel/

 components  of a  photosensitive foil:-TMD
tungsten diselenide
 -and contacts of gold
-spanned by a layer of conducting graphene

TMD is Transition-metal dichalcogenide  and is only 6.5 Å thick.
https://en.wikipedia.org/wiki/Transition_metal_dichalcogenide_monolayers

tungsten diselenide is:
chem-  Se=W=Se    (Se symbol of selenium)
https://en.wikipedia.org/wiki/Tungsten_diselenide

where W symbol  is Wolfram  known also as Tungsten
https://en.wikipedia.org/wiki/Tungsten

Thickness of the gold contact is  expected to be in ~ tens of  nm.
One gram of gold can be stretched any where between 2.99 to 3 km approx.=2.1 mile.
https://www.quora.com/How-many-km-a-1gm-of-gold-can-be-stretched
-so it is unlikely  that  gold will  grow in price because of that

But  the energy density  or  energy per unit  is not  known to me yet.
