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.

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

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.
