我们报道了一种提高性能的多尺度织构黑硅太阳能电池的功率转换效率为15.5%，通过使用各向异性的四甲基氢氧化铵蚀刻控制复合。多尺度织构可以有效地降低样品在宽波长范围内的表面反射率，并且在n++发射极形成后对样品进行刻蚀可以有效地抑制表面复合和俄歇复合。我们的结果表明，改造后的太阳能电池有更高的转换效率比传统的金字塔织构电池（15.3%）。这项工作为提高纳米结构硅太阳电池的性能提供了一种有效的方法。
We report an enhanced performance of multi-scale textured black silicon solar cell with power conversion efficiency of 15.5% by using anisotropic tetramethylammonium hydroxide etching to control the recombination. The multi-scale texture can effectively reduce the surface reflectance in a wide wavelength range, and both the surface and Auger recombination can be effectively suppressed by etching the samples after the n++ emitter formed. Our result shows that the reformed solar cell has higher conversion efficiency than that of conventional pyramid textured cell (15.3%). This work presents an effective method for improving the performance of nanostructured silicon solar cells.
