摘要

在TiO2层上沉积铟纳米粒子(In NPs)并覆盖Al2O3层，证明了硅太阳能电池的光伏性能增强。这种令人印象深刻的性能增强归功于基于Al2O3/TiO2抗反射的In NPs宽带光散射。测量并比较了不同厚度TiO2层的光学反射率、光伏电流电压和外量子效率。在Al2O3 (65 nm)/TiO2 (20 nm)结构中嵌入In纳米粒子，效率提高54.5%(从10.96%提高到16.93%)。

Photovoltaic performance enhancement of plasmonics silicon solar cells using indium nanoparticles embedded in Al2O3/TiO2 layer structure

The photovoltaic performance enhancement of silicon solar cells depositing indium nanoparticles (In NPs) on TiO₂ layer and capping an Al₂O₃ layer was demonstrated. The impressive performance enhanced was attributed to the In NPs broadband light scattering based on Al₂O₃/TiO₂ antireflection. The optical reflectance, photovoltaic current-voltage, and external quantum efficiency were measured and compared with various thickness of TiO₂ layer. The efficiency enhancement of 54.5% (from 10.96% to 16.93%) was obtained when the cell with In NPs embedded in the Al₂O₃ (65-nm)/TiO₂ (20-nm) structure.
