H01L 31/18
PCT/CN2013/087239CSI CELLS CO., LTDSU, Xiaodong
A manufacturing method for a textured structure of a crystalline silicon solar cell, comprising the following steps: (1) cleaning and texturing; (2) immersing a silicon wafer in a solution containing metal ions, such that the surface of the wafer is coated in a layer of metal nanoparticles; (3) corroding the surface of the silicon wafer to form a nanotextured surface; (4) cleaning off the metal particles; (5) immersing in a second chemically corrosive liquid to implement micro-structural corrective etching; (6) cleaning and spin-drying. On the basis of the present method, the size of the manufactured textured structure is 100-500nm, the structure presenting nanometer pores or edged nanometer pyramids or edged nanometer cones or edged nanometer pits of shallow depth and large diameter. The conversion efficiency of the cell is thereby increased.
