一种局部背接触太阳能电池的制备方法技术

一种局部背接触太阳能电池的制备方法，包括如下步骤：去除硅片表面损伤层并进行双面抛光、制绒、形成PN结、刻蚀和去杂质玻璃、背面沉积钝化膜、正面沉积钝化减反射层、背面局部开口、丝网印刷正背面金属浆料、烧结；其中，制绒步骤采用金属催化腐蚀法，其绒面结构为纳米级绒面结构。将去除硅片表面损伤层和双面抛光结合成一步工序来实现，简化了工艺流程，降低了成本。

Preparation method of a local back contact solar cell

The preparation method of a local back contact solar cell includes the following steps: removing the surface damage layer of the silicon wafer and polishing the surface of the silicon surface, making the cashmere, forming the PN junction, etching and removing impurity glass, the passivation film on the back deposition, the passivation antireflection layer on the front deposition, the back partial opening, the wire mesh printing and the positive back metal paste, and sintering; Among them, metal catalytic corrosion is used in the process of making the pile, and its texture is nano scale suede structure. The damage surface of silicon wafer and the double-sided polishing are combined into one step to simplify the process and reduce the cost.
