Abstract

The HNO3/HF solutions etching has been used to improve the properties of the black silicon for solar cells. The effect of the HNO3/HF ratio and etching time on the black silicon has been investigated by scanning electron microscope, UV-VIS-NIR spectrophotometer, external quantum efficiency and I-V test system. Results show that the HNO3-rich HF-HNO3 solution etching can optimize the structure and remove the damage of the black silicon. After acid etching, the efficiency of the black silicon solar cell can be improved by 1%.
