Realizing an excellent spectral response by utilizing the ultraviolet parts of solar radiation is an important focus for enhancing the performance of photovoltaic cells (PCs). Pr3+ and Eu3+ ions co-doped multifunctional transparent GdPO4 glass-ceramic is successfully prepared using a conventional melting quenching technique. In GdPO4: Pr3+-Eu3+, ultraviolet to visible downshifting is realized via the remarkable energy transfer from Pr3+ to Eu3+ ions by bridge Gd3+ ions. Introducing the spectral conversion material by converting ultra-violet photons into visible photons is considered a very promising route; it can be applied to perovskite PCs by reducing the photo-degradation and enhancing the light harvesting, and it can be applied to hydrogenated amorphous-silicon carbide PCs by reducing the solar energy losses associated with spectral mismatch of the spectral response and energy. The development of downshifting Pr3+-Eu3+ co-doped glass-ceramics might open up a new approach to achieving a better performance of photovoltaic devices.

用于光伏电池应用的紫外线波长驱动的太阳能光谱转换器

利用太阳辐射的紫外部分实现优异的光谱响应是增强光伏电池（PC）性能的一个重要焦点。采用常规熔融淬火技术成功制备了Pr3+和Eu3+离子共掺杂多功能透明GdPO4微晶玻璃。在 GdPO4: Pr3+-Eu3+ 中，紫外光到可见光的下移是通过桥 Gd3+ 离子从 Pr3+ 到 Eu3+ 离子的显着能量转移实现的。引入光谱转换材料，将紫外光子转换为可见光子，被认为是一条非常有前途的途径；它可以通过减少光降解和增强光收集来应用于钙钛矿PC，并且可以通过减少与光谱响应和能量的光谱失配相关的太阳能损失来应用于氢化非晶碳化硅PC。降频Pr3+-Eu3+共掺杂玻璃陶瓷的开发可能为实现更好的光伏器件性能开辟新途径。
