| 摘 要： | 该文旨在利用银纳米颗粒（Ag NPs）和SiOx/Ag背反射结构提升硅异质结（SHJ）太阳电池在900~1200nm波段红外光谱响应。研究在SHJ太阳电池背光侧分别制备Ag、SiOx/Ag和嵌入Ag NPs的SiOx/Ag几种背反射结构,以最大限度提升SHJ太阳电池红外光谱响应。结果表明：SiOx/Ag背反射结构可有效减少红外光的逃逸损失,提升太阳电池红外光谱响应,使得双面制绒SHJ太阳电池短路电流密度从37.74 mA/cm2提升到38.07 mA/cm2;但嵌入Ag NPs并不能帮助SiOx/Ag背反射结构进一步提升双面制绒SHJ电池红外光谱响应,证明了基于其局域表面等离激元共振效应仅对陷光能力较差的平面太阳SHJ电池有一定提升。

| Abstract: | This paper aims to use silver nanoparticles （Ag NPs） and SiOx/Ag back reflection structure to improve the infrared spectral response of silicon heterojunction （SHJ） solar cells in the 900-1200 nm band. By preparing the SiOx/Ag back reflection structure on the back side of the SHJ solar cell, and embedding Ag NPs in the SiOx film, an attempt was made to superimpose the Ag NPs and the SiOx/Ag back reflection structure to maximize the infrared spectral response of the SHJ solar cell. The results show that the SiOx/Ag back reflection structure can effectively reduce the escape loss of infrared light and improve the infrared spectral response of the solar cell, so that the short-circuit current density of the textured SHJ solar cell is increased from 37.74 mA/cm2 to 38.07 mA/cm2. However, the embedded Ag NPs cannot help the SiOx/Ag back reflection structure to further improve the infrared spectral response of the textured SHJ solar cell, which proves that the local surface plasmon resonance effect is only effective for the flat SHJ solar cell with poor light trapping ability. |
