Neat!
I am sure they will also amp this up by somehow employing graphene into this mix as well.
As good as this news is, keep in mind that solar cells will be instantly and totally destroyed by any EMP. That is due to their very construction, that is the “PN junction” they all rely upon and the current-collection grid they all must have. The voltage spike induced by the EMP cannot be mitigated by the external diodes commonly used because of the sharp rise time of the Pulse. There is NO way around this. PV cells WILL be destroyed in an EMP attack. Almost certainly the vast majority of them.
