In this work, we report an easy, efficient method to synthesize high quality lithium-based upconversion nanoparticles (UCNPs) which combine two promising materials (UCNPs and lithium ions) known to enhance the photovoltaic performance of perovskite solar cells (PSCs). Incorporating the synthesized YLiF:Yb,Er nanoparticles into the mesoporous layer of the PSCs cells, at a certain doping level, demonstrated a higher power conversion efficiency (PCE) of 19%, additional photocurrent, and a better fill factor (FF) of 82% in comparison to undoped PSCs (PCE = ~16.5%; FF = 71%). The reported results open a new avenue toward efficient PSCs for renewable energy applications.
在这项工作中，我们报告了一种简便、高效的方法来合成高质量的锂基上转换纳米颗粒（UCNPs），该方法将两种已知能提高钙钛矿太阳能电池（PSC）光伏性能的有前景的材料（UCNPs和锂离子）结合在一起。将合成的YLiF:Yb,Er纳米颗粒掺入PSC电池的介孔层中，在一定掺杂水平下，与未掺杂的PSC（PCE = ~16.5%；FF = 71%）相比，展现出了更高的功率转换效率（PCE），达到19%，额外的光电流，以及更好的填充因子（FF），为82%。所报道的结果为可再生能源应用的高效PSC开辟了一条新途径。
