基于纳米锥结构的钙钛矿材料吸收特性研究

Study on absorption characteristics of perovskite materials based on nano-cone structure

本文对ZnO结构太阳能电池钙钛矿(CaTiO3)薄膜层中嵌入的Ag粒子的等离子体增强进行了理论分析。由于引入了Ag颗粒,归因于Ag颗粒的强表面等离子体吸收和Ag与CaTiO3之间的协同作用,太阳能电池的吸收得以增强。在计算分析中,Ag粒子的最佳半径为80 nm。优化的纳米结构的平均吸收效率可以达到80%,比纯CaTiO3薄膜层结构的平均吸收效率高24%。因此认为,本文设计研究的Ag/CaTiO3太阳能电池结构可能以低成本和简单的制造工艺成为未来工业制造领域的焦点。

In this work,a theoretical analysis of plasmonic enhancement of Ag particles embedded in CaTiO3 thin-film layer for ZnO structure solar cells is presented.Due to the introduction of Ag particles,the absorption of solar cell is enhanced,owning to the strong surface plasmon absorption of Ag particles and synergistic effect between Ag and CaTiO3.In our analysis,the optimized radius of Ag particles is 80 nm.The average absorption efficiency of the optimized nano-structure can achieve 80%,which is 24% higher than that of pure CaTiO3 thin-film layer structure.We believe the proposed Ag/CaTiO3 solar cells structure could be a potential candidate for futureindustry manufacture with low-cost and simple fabricationprocess.
