Interesting and it sounds promising like all of these ideas and “breakthroughs” do.
There is one guarantee in the world of energy - change. Yesterday, tomorrow, and next year there is innovation and something new. Eventually, there will be new ideas that radically changes energy so much of the “debate” we see today may be meaningless tomorrow.
A free market in such things as this is wonderful. What isn’t wonderful is when government arbitrarily picks a winner, even if it is not the best in class (e.g. Solyndra).
It is because of relentless competition to improve in engineering that we went from the vertical scans of Stooky Bill to the flat panels that most of us are sitting before, if not using their miniature version in smartphones. Let good solutions give place to better, and then even better, solutions.
Quiet revolutions like this, rather than government fiats (which are ludicrous in technological fields), could evolve the world past the need for fossil fuels, if other events do not intervene. I don’t think technology is going to be the bottleneck for mankind. I think spirituality will be.
“Stranks’ enthusiasm has to be tempered with some unpleasant realities. Keith Emery, who compiles the National Renewable Energy Laboratory’s solar cell efficiency data, explains why perovskites need a disclaimer. “The samples degrade very quickly to zero. They degrade fast enough that it has prevented intercomparing results among groups or even having an independent efficiency measurement.” Light, air and water are all kryptonite to perovskites, according to NASDAQ.com. “
Graphene sounds exotic compared to hemp. Yet hemp turns out to be a better dielectric than graphene for storing electricity in capacitors. So would hemp work even better than the perovskite in the solar cells?
