‘Miracle material’ smashes solar panel efficiency threshold
https://www.independent.co.uk/tech/p...-b2371954.html
Tesla solar panels are 19-20% efficient. Leading panels are 23%. Average panels are 15-20%. These panels just set a leap in efficiency by 50-100% to a new record of 33.7%, and they are cheap. A Chinese startup will be producing their version of this technology at 1/20th of the price of traditional solar cells. We will see if that turns out to be true.
As the gentleman said in the TED Talk above, solar is much more of a technology than other forms of energy production, and as such is the case, it should be viewed in that light in how it will improve and get better and cheaper. Steam turbines could see some improvements in efficiency for nuclear, gas or coal, but it is unlikely. Blade technology could advance for wind, but again, that is different than solar panel tech, which has more parity with cell phones, TVs and computers.
