Near-Infrared Quantum Cutting Nanophosphors for Solar Cells

Abstract:

An efficient near-infrared (NIR) quantum cutting (QC) nanophospors with Ce³⁺, Yb³⁺ codoped in CaF₂ had been synthesized by hydrothermal method and characterized by X-ray powder diffraction, scanning electron microscope, transmission electron microscopy, photoluminescence spectra and decay dynamics. The nanoparticles were uniform and monodisperse. Under the excitation of 5d level of Ce³⁺, an intense NIR emission at 900-1050nm was observed which match to the energy of Si band gap of Si - based solar cells. In the Ce³⁺, Yb3⁺ codoped CaF₂, the lifetime of Ce³⁺ decreases ^{Superscript text}and the quantum efficiency (QE) increases with increasing Yb³⁺ concentration.
