An efficient light converter YAB:Cr³⁺,Yb³⁺/Nd³⁺ with broadband excitation and strong NIR emission for harvesting c-Si-based solar cells

Abstract

The Cr³⁺–Yb³⁺ co-doped YAB could convert almost high-energy UV-Vis photons into low-energy NIR photons efficiently, which benefits the enhancement of silicon solar photovoltaic conversion efficiency.
