The inverted pyramid microstructures (IPMS) were fabricated jointly by metal-assisted chemical etching (MACE) technology with extremely low concentration of silver ions to formed nanopores and nanostructure rebuilding (NSR) treatment of NH 4 HF 2 solution. The results show nanopores were achieved with the aid of Ag-MACE technology, which diameter was mainly affected by the action of Ag ions, and depth was yet mainly influenced by HF concentration. Textured IPMS single-crystalline silicon (sc-Si) solar cells with the diameter of 1 μ m and reflectivity of 8.62% were large-scale prepared. Benefiting from better light-trapping ability, the photoelectric conversion efficiency of IPMS sc-Si solar cells in standard size of 156.75 × 156.75 mm 2 achieved 22.06%. Simultaneously, the short-circuit current was increased by 71 mA. This promising technology could become a viable solution for industrial production of highly efficient sc-Si solar cells in the ...

通过纳米结构重建处理大规模制备具有倒金字塔形结构的22.06％效率的单晶硅太阳能电池

倒金字塔结构（IPMS）是通过金属辅助化学刻蚀（MACE）技术与极低浓度的银离子形成纳米孔并用纳米结构重建（NSR）处理NH 4 HF 2溶液共同制造的。结果表明，借助Ag-MACE技术获得了纳米孔，其直径主要受Ag离子作用的影响，而深度却主要受HF浓度的影响。大规模制备了直径为1μm，反射率为8.62％的纹理IPMS单晶硅（sc-Si）太阳能电池。受益于更好的光捕获能力，标准尺寸为156.75×156.75 mm 2的IPMS sc-Si太阳能电池的光电转换效率达到22.06％。同时，短路电流增加了71 mA。
