Dye-sensitized solar cell

That transitioned into what's known as dye-sensitized solar cells.

And then shortly after DSSC, dye-sensitized solar cells, evolved into perovskite so the first perovskite solar cell on record that was ever published was back in 2011 by Miyasaka-san I believe I'm at a Japanese university don't want to cite a specific one and give credit where credit's not due but that was back in 2011 and since then it's had a meteoric rise in efficiency that's been unrivaled by any other viable solar technology Up to where I believe the record today for a single junction perovskite cell is around 27.2, 27.3%.

Please go back and reference NREL.

It does a good job of coagulating a lot of this data and publishing it available for everyone.
