Embodiment 1
[0026] Embodiment 1: as image 3 As shown, the form of four-sided overflow is adopted to accelerate the flow and renewal of the liquid, take away the heat released by the reaction of the silicon wafer, and ensure the uniformity of the reaction temperature and concentration of the silicon wafer, thereby ensuring a better texturing effect.
[0027] A method for chain texturing of polycrystalline solar cells, comprising the following steps:
[0028] Step 1: Adopt the four-sided overflow method of the tank body, so that the liquid overflows quickly after the reaction;
[0029] Step 2: adopt the upper spray method; in the upper part of the liquid medicine tank, a certain number of spray pipes 2 are added, and the liquid medicine is directly replenished around the silicon chip 3 from the upper part; this makes the liquid medicine and the Wafer contact more fully, and at the same time It also makes it easier to control the temperature of the liquid medicine, keep it uniform and impr...
