Will luminescent solar concentrators surpass the 10% device efficiency limit?

We also prepared luminescent nanocrystals with different shapes—either dot-core (the core is a spherical dot), rod-shell (the shell is more of a rod and non-spherical), or core/multishell (both core and multishell are spherical)—and determined their reabsorption.10For Type I (cadmium selenide, CdSe), Type-II-iso (cadmium telluride / cadmium selenide / zinc sulfide, CdTe/CdSe/ZnS core/multishell), and Type-II-an (CdTe/CdSe dot-core/rod-shell) nanocrystals, the self-absorption cross sections were 52.2%, 2.5%, and 0.2%, respectively. LQE of the nanocrystals was 27% and 48%, for CdSe, and Type-II-iso nanocrystals, respectively.
