The texturing process with alkaline solution added a new additive on single-crystal silicon surface was discussed.At different times,alkaline solution added a new additive was used to etch the Si wafers,and samples were scanned by scanning electron microscopy.The results show that there are a few different size pyramids and smooth regions in large-area on the Si surface after etching 10 min; after etching 15 min,the sizes of pyramids become uniform,and the areas of smooth regions will reduce; after etching 20 min,the etched surface is covered with the 2~4 μm of pyramids,and the distribution is more uniformly-densely; after etching 25 min,the sizes of pyramids increase again in the over-etching process.The experiments illustrate that the new additive can effectively reduce the texturing time,make an ideal textured structure,and be applied in industry.
