UCLA professor Yang Yang, member of the California NanoSystems Institute, is a world-renowned innovator of solar cell technology whose team in recent years has developed next-generation solar cells constructed of perovskite, which has remarkable efficiency converting sunlight to electricity.
Despite this success, the delicate nature of perovskite—a very light, flexible, organic-inorganic hybrid material—stalled further development toward its commercialized use. When exposed to air, perovskite cells broke down and disintegrated within a few hours to few days. The cells deteriorated even faster when also exposed to moisture, mainly due to the hydroscopic nature of the perovskite.
Now Yang's team has conquered the primary difficulty of perovskite by protecting it between two layers of metal oxide. This is a significant advance toward stabilizing perovskite solar cells. Their new cell construction extends the cell's effective life in air by more than 10 times, with only a marginal loss of efficiency converting sunlight to electricity.

Who fixes their robots when they break? Who corrects the code when they mis-behave? Who will they imagine will fawn over them and constantly tell them they're the greatest thing since sliced bread?
I bet you Jamie Dimon doesn't even know how to operate a power drill. Lloyd Blankfein has probably never done a single creative or productive thing in his life--parasites never do.
Their bunkers will fill with ground water as pumps fail and filters clog. The sound system will fail because rodents have gnawed through the wires. The tinned caviar will go off because it wasn't properly sterilized before sealing. The little crumpets produced by that lovely baker in Surrey can no longer be had at any price. Spoiled infants, surrounded by broken toys, squalling for somebody to come along and change their diaper.
Washington DC delenda est.
