摘要

我们报告了一种生产掺杂镧系离子的氟化锂基纳米晶体（YLiF4）的简单而有效的方法。我们利用这些纳米粒子在制造的过氧化物太阳能电池中进行上转换。结果表明，上转换 YLiF4:Yb, Er 纳米粒子改善了二氧化钛和过氧化物层界面的能级排列。这使得所制造的过氧化物太阳能电池的功率转换效率从 19.45% 提高到 21.32%。为了更好地理解重组机制及其与导带偏移和缺陷的相关性，器件模型被额外集成到 SCAPS 模拟器中。随后，获得的 J-V 模拟结果与实验观测结果呈现出良好的一致性。

Enhanced performance of perovskite solar cell via up-conversion YLiF4:Yb, Er nanoparticles

We report a simple and effective method for producing lanthanide ion-doped lithium-fluoride-based nanocrystals (YLiF₄). We utilized those nanoparticles for up-conversion in fabricated perovskite solar cells. The obtained results shows that the up-conversion YLiF₄:Yb, Er nanoparticles improve alignment of energy levels at interface between titanium dioxide and perovskite layer. This increases power conversion efficiency of fabricated perovskite solar cells from 19.45 % to 21.32 %. To enhance comprehension of the recombination mechanism and its correlation with the conduction band offset and defects, device models are additionally integrated into the SCAPS simulator. Subsequently, the obtained J-V simulation outcomes exhibit a favorable concordance with the experimental observations.
