本文研究了薄膜硅太阳电池中绒面背反射镜的陷光效应。利用铝的阳极氧化作为一种自有序过程，研制出了一种具有周期性凹坑图案的独特基底。在Al衬底上制造的周期为0.9 μ m的n-i-p氢化微晶Si（μ c-Si：H）电池与在随机纹理衬底上制造的电池相比显示出改进的红外响应。在1 μ m厚的μ c-Si：H电池中，采用图案化的Al衬底获得了24.3mA/cm（2）的高短路电流密度。(C)2008年美国物理学会。[DOI：10.1063/1.2993351]
In this article, the light-trapping effect of textured back surface reflectors in thin-film Si solar cells is investigated. A unique substrate with a periodic dimple pattern has been developed by utilizing anodic oxidation of Al as a self-ordering process. n-i-p hydrogenated microcrystalline Si (mu c-Si:H) cells fabricated on the Al substrate with a period of 0.9 mu m show an improved infrared response compared to those fabricated on randomly textured substrates. A high short circuit current density of 24.3 mA/cm(2) has been achieved in a 1-mu m-thick mu c-Si:H cell by adopting the patterned Al substrate. (C) 2008 American Institute of Physics.
