Title: Stanford's new solar electric cell
Post by: Floor on January 03, 2022, 12:50:17 AM

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/ (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 (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 (https://en.wikipedia.org/wiki/Tungsten_diselenide)

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