将一个紫外光子切割成三个近红外光子可以有效地提高硅太阳能电池的效率。我们制备了Yb掺杂、pr掺杂和Yb/ pr共掺杂的NaY(WO4)(2) （NYW）晶体。Yb/ pr共掺杂样品可以将紫外光子和蓝光光子分解为类似于1000 nm的近红外光子，在近红外波长范围内具有较强的发射性。根据发光光谱和寿命分析，该材料的量子效率较高。(C) 2014 Elsevier B.V.版权所有
Cutting one ultraviolet photon into three near-infrared (NIR) photons can effectively improve the efficiency of silicon solar cells. We prepared Yb-doped, Pr-doped, and Yb/Pr-codoped NaY(WO4)(2) (NYW) crystals. The Yb/Pr-codoped sample can divide the ultraviolet and blue photons into similar to 1000 nm NIR photons, which brings strong emission at the NIR wavelength range. On the basis of the luminescence spectra and lifetime analysis, the quantum efficiency of the material is higher. (C) 2014 Elsevier B.V. All rights reserved.
