Dual Spectral Matching in Perovskite Solar Cells via Upconverting plus Downshifting Nanoparticles.

ABSTRACT: Maximizing solar cell efficiency is a critical step toward revolutionizing photovoltaic technologies and harnessing the full potential of light for energy conversion. This study investigates the incorporation of NaGdF₄:Yb³⁺,Tm³⁺@NaGdF₄:Eu³⁺ (TMN) and NaGdF₄:Yb³⁺,Er³⁺@NaGdF₄:Eu³⁺ (ERN) nanoparticles into perovskite solar cells (PSCs) to improve their power conversion efficiency. The nanoparticles were synthesized through thermolysis and characterized using multiple techniques, including photoluminescence spectroscopy, quantum yield measurements, transmission electron microscopy, X-ray diffraction, solar simulation, and external quantum efficiency assessments. These lanthanide-doped
