摘要

Abstract

Luminescent solar concentrators (LSCs) offer a sustainable approach to power generation using fluorescent glasses

yet their green industrialization is impeded by the limited production scale and non-recyclability of embedded nanocrystals. Here

we introduce a lead-free perovskite derivative ETP

SbCl

(ETP = (C

)

) with a reversible transition between powder and glass states. Through molecular dynamics and density functional theory

we elucidate the possible structural distortions of [SbCl

]

pyramids and their impact on luminescence. The fabricated LSCs

utilizing such fluorescent glasses with an efficient absorption for

420 nm

achieve the highest power conversion and optical efficiencies of ~5.56% and ~32.5%

respectively. In addition to self-healing by reheating at ~200 ℃

impressively

it could be mass recycled to phosphor by ethanol or heating treatments

which still maintains nearly initial fluorescent perf

ormance and could be repurposed like freshly synthesized samples. This work presents a paradigm for the sustainable use of fluorescent materials and offers a reliable path toward low-carbon globalization.
