A novel application of near-infrared quantum splitting (NIR QS) that splits one ultraviolet-visible photon into NIR multiphotons can be developed for solar energy conversion. In this paper, we theoretically investigate the underlying mechanism of NIR QS in Ho³⁺ single- and Ho³⁺-Yb³⁺ dual-doped &#x03B2;-NaYF₄ by modeling and solving rate and power propagation equation system. The highest quantum efficiency is estimated to be 257% among studied systems. The total amount of output NIR photons may be increased to meet the purpose of potentially enabling a Si-cell with a photoelectric conversion efficiency enhancement. This paper could benefit for further exploring a promising NIR QS system in the exciting field of photonic devices and materials.
