Breaking max efficiency of solar cells by activating 2 electrons with 1 photon

This is incredible. I mean it&#x27;s a long way to seeing this in affordable silicon solar cells, but still amazing to me that the materials engineering can accomplish things like this.<p>It leads to roughly a twenty percent boost in theoretical max efficiency. If that can be translated to a twenty percent actual improvement, that&#x27;s huge.

&quot;2 electrons with 1 photon&quot; --- that is how photosynthesis works in nature. Great thinking!

Interesting how &quot;through a process called singlet exciton fission&quot; and other article &quot;General Formula for Bi-Aspheric Singlet Lens Design Free of Spherical Aberration&quot; [1] both deal with Singlets. Odd coincidence of the day.<p>[1] <a href="https:&#x2F;&#x2F;www.osapublishing.org&#x2F;ao&#x2F;abstract.cfm?uri=ao-57-31-9341" rel="nofollow">https:&#x2F;&#x2F;www.osapublishing.org&#x2F;ao&#x2F;abstract.cfm?uri=ao-57-31-9...</a>

This is great - but isn’t hafnium pretty rare?

So is two the most possible? Is it possible to activate three electrons with a single photon?

Pardon my ignorance but don&#x27;t avalanche photodiodes, scintillators, phosphors, etc. excite many electrons per 1 photon? Why is 2 electrons for 1 photon noteworthy?

I&#x27;m glad to see Baldo has moved on from useless experiments on hexacene. Sincere congratulations to him and his group.

I mean it all means bunk till a mass produced product is on the shelves. A lot of these “breakthrus” fail to note edge cases like scalability, durability
