Abstract:
This study focuses on synthesizing the heavy metal-free ancient
Egyptian blue (EB; CaCuSi4O10) dye using a facile ceramic method
for luminescent solar concentrator (LSC) application. XRD, SEM
and EDX results confirmed that this well-crystallized material is
successfully synthesized. Optical studies revealed that EB has a high
Stokes shift and possesses an average lifetime of 110.50 ls with a
quantum yield of 12.93%. Finally, an EB-integrated LSC was fabricated
that exhibits a power conversion efficiency (g) of 0.15% and
an optical conversion efficiency (gopt) of 1.21%, which are the
highest values reported so far using EB.
