Perovskites

This is such a big industry now that I would expect a constant stream of minor improvements and the occasional big step.
Houses need low cost per watt. Efficiency is of less importance until you need every watt.
RVs need better efficiency so they can get more watts on the roof.
Looks like this might give both?
Cheers,

Oxford PV achieved 28% efficiency 2 years ago:

There are some downsides to this technology:

Until I read your second article, Dorian. I thought that it may have been a very big breakthrough

Perhaps this is another one of those "wait and see" future solar panel products

I have no doubt that as Peter has already said, with the industry getting larger, there will be more breakthroughs, down the line

I read (many years ago) about future battery technology, so I assume that it will be the same for solar panels

The theory was at that time, that not enough deep cycle/electric car batteries were being sold, to entice the research for a better battery

Now with more and more, deep cycle/electric car batteries being sold, we seem to be getting better batteries

Yea well I read a bit of that and went to a '2nd gen' reference but hell I soon started to bog down !! disbelief

Get this bit; "Scientists from the South Dakota School of Mines and Technology and Michigan State, Toledo and Wisconsin universities bla bla-----.

The scientists examined sites at Toledo, in Ohio and Golden, Colorado, to take account of high and low latitude and humidity conditions. The researchers analyzed the environmental impact of single-junction, bifacial perovskite cells with high and low bandgaps, and multi-junction devices of the same type with two-terminal (2T) and four-terminal (4T) structures. They quantified the life cycle energy production from the cells under real-world conditions and benefiting from diverse albedo environments including installation above sandstone, concrete, grass and snow."

Now who is going to argue with that Jargonese biggrin it could be right !

My mate, who might know a bit more than most, said he knew about perovskite, and he was not a Russian spy like I thought smile smile

When the patent lawyers get involved, even the scientists won't understand it.
