| 摘 要： | 采用银金属催化化学腐蚀（Ag-MCCE）技术在碱腐蚀的金字塔微米初级绒面结构上制备均匀的纳米次级绒面结构,并研究银纳米颗粒在微米金字塔表面的附着特性及其对纳米结构均匀性和电池性能的影响。结果表明,通过添加聚乙烯吡咯烷酮（PVP）可改善银纳米颗粒在微米金字塔表面的附着均匀性,制备的纳米结构在微米金字塔结构表面分布均匀,且便于后道SiNx的钝化;制得的单晶PERC电池平均效率达到22.22%,较未改善的对比组提升0.46%;独特的微-纳复合绒面（NOM-texture）可实现单晶太阳电池的全角度陷光,兼顾新型光伏屋顶等光伏建筑一体化（BIPV）场合对电池高转换效率和准全向外观的双重要求。

| Abstract: | In this work, the nano-scaled structures have been uniformly fabricated on alkali-etched micron-scaled pyramid-structures by Ag metal-catalyzed chemical etching technique. The deposition characteristic of Ag nanoparticles on micron pyramid-structures and its influence on the uniformity of nanostructure were studied, as well as on the performances of the mono-Si PERC （Passivated Emitter and Rear Contact） solar cells. The results show that the distribution uniformity of Ag nanoparticles deposited on the micron pyramid-structures can be improved by using polyvinylpyrrolidone as an additive. The prepared nanostructures are uniformly distributed on the micron pyramid-structures and are easy to be passivated by the subsequent SiNx. The average efficiency of the fabricated mono-Si PERC cells is 22.22%, which is 0.46% higher than that of the control group without the additive. The all-angled light trapping property for silicon solar cells can be realized by forming the unique nano-on-micron texture （NOM-texture）, which can meet the requirements of Building Integrated Photovoltaics such as new Solar Roof on the high efficiency and quasi-omnidirectional appearance of the cells. |
