Highly efficient large-area luminescent solar concentrators (LSCs) were demonstrated using colloidal C-dots. The large-area LSC (225 cm2) exhibited an external optical efficiency of 2.2% (under natural sun irradiation, 60 mW cm−2).
Luminescent solar concentrators (LSCs) are large-area sunlight collectors, consisting a waveguide embedded with fluorophores LSCs could reduce the use of expensive silicon solar cells, thus decreasing the cost of the...
