The present invention provides a method for producing a solar cell module; the present invention is characterized in that: in the process of soldering and connecting crystalline silicon solar cells, the crystalline silicon solar cells are kept still at positions on a bottom layer, and soldering and connecting of all crystalline silicon solar cells are implemented by moving a soldering apparatus or by moving the bottom layer; by means of the method for soldering and connecting crystalline silicon solar cells in the present invention, the process of soldering and connecting crystalline silicon solar cells is simplified and accelerated, and meanwhile, problems such as hidden fractures and power attenuation of the module occurring in the process of soldering and connecting solar cells are resolved.

Method for producing solar cell module

The disclosure includes a laser soldering method of connecting crystalline silicon solar batteries. Methods can include placing conductive soldering strips and crystalline silicon solar batteries on a lower press plate and aligning the conductive soldering strips on metal electrodes of crystalline silicon solar batteries. Methods can also include placing an upper press plate on the conductive soldering strips and the crystalline silicon solar batteries and vacuuming between the upper and lower press plates such that absolute pressure between the upper and lower press plates is less than atmospheric pressure. Methods can also include laser soldering the conductive soldering strips and the crystalline silicon solar batteries.

Laser soldering systems and methods for joining crystalline silicon solar batteries

An acid corrosion solution for preparing polysilicon suede is obtained by mixing with an oxidant and a hydrogen fluoride. The oxidant is a nitrate or nitrite. The method applied of the solution includes putting the polysilicon cut pieces into the acid corrosion solution to carry out the corrosion reaction. The reaction time is about 30 seconds to 20 minutes and the temperature of acid corrosion solution is &#x2212;10&#xb0; C. to 25&#xb0; C.
