Owing to small size effect and large surface area, silver nanoparticles (Ag NPs) exhibit special physical properties and are widely used in different applications. One of the significant applications is that Ag NPs can be coated on the glass surface of solar cell to increase the light-harvesting efficiency of solar cell due to the plasmonic resonance and scattering effect. In this study, Ag NPs used for the coating of solar cells were synthesized via a chemical reduction method. The effect of the concentration of sodium borohydride (NaBH₄) as reducing agent and 1-dodecanethiol (DDT) as capping agent on the size and shape of Ag NPs synthesized have been investigated. The synthesized Ag NPs were characterized using UV–vis spectroscopy, X-ray diffraction, energy-dispersive X-ray spectrometry and ATR-FTIR spectroscopy; while the particle size, morphology and topology of Ag NPs were examined by scanning electron microscopy and atomic force microscopy. By coating the glass surface of amorphous silicon solar cells with a uniform array of Ag NPs with the particle size of > 350 nm, a power conversion efficiency (PCE) enhancement of approximately 41% has been achieved. (3-mercaptopropyl) trimethoxysilane (MPTMS) was used as the adhesion promoter to anchor Ag NPs on the silicon surface of solar cells. With 7% of MPTMS, the array of Ag NPs formed on the glass surface was found being the most evenly distributed with a densely packed surface coverage, which resulted in 46% of PCE enhancement of the silicon solar cells.

由于小尺寸效应和大表面积，银纳米颗粒（Ag NPs）表现出特殊的物理性能，并广泛用于不同的应用中。重要的应用之一是由于等离子体共振和散射效应，可以将Ag NPs涂覆在太阳能电池的玻璃表面上，以提高太阳能电池的集光效率。在这项研究中，通过化学还原法合成了用于太阳能电池涂层的Ag NPs。硼氢化钠（NaBH ₄）作为还原剂，1-十二烷硫醇（DDT）作为封端剂对合成的Ag NP的大小和形状进行了研究。使用紫外可见光谱，X射线衍射，能量色散X射线光谱和ATR-FTIR光谱对合成的Ag NP进行表征。用扫描电镜和原子力显微镜观察了银纳米颗粒的粒径，形貌和拓扑。通过用粒径大于350 nm的均匀排列的Ag NP阵列覆盖非晶硅太阳能电池的玻璃表面，可以实现约41％的功率转换效率（PCE）增强。使用（3-巯基丙基）三甲氧基硅烷（MPTMS）作为附着力促进剂，将Ag NP锚定在太阳能电池的硅表面上。拥有7％的MPTMS，
