Dry and wet machine and production line

Abstract

The invention provides a dry-wet all-in-one machine, which comprises a slice inserting and feeding machine, an automatic front cleaning machine, an automatic feeding and blanking mechanism, an RIE wet-method texturing machine, an automatic lamination stacking machine and a flower basket automatic-rotating mechanism, wherein the slice inserting and feeding machine, the automatic front cleaning machine and the automatic feeding and blanking mechanism are connected in sequence; the RIE wet-method texturing machine and the automatic lamination stacking machine are respectively connected with the automatic feeding and blanking mechanism, and the flower basket automatic-rotating mechanism is arranged between the slice inserting and feeding machine and the automatic front cleaning machine. According to the whole set of equipment provided by the invention, in order to implement a wet-method texturing process of silicon slices, the processes and the technologies such as automatically inserting the silicon slices, performing front cleaning, automatically switching the silicon slice onto the wet-method texturing machine, performing wet-method texturing, and automatically laminating the silicon slices are integrated. The whole set of equipment does not need manual intervention as automatic equipment is used. On the basis, the invention also provides a production line adopting the dry-wet all-in-one machine.

Description

technical field [0001] The invention relates to the field of solar cell manufacturing, in particular to a dry-wet integrated machine and a production line. Background technique [0002] In solar cells, in order to reduce the reflection of silicon wafers on sunlight, light energy is converted into electrical energy as much as possible to improve power generation efficiency. Before the silicon wafer is made into a cell, the surface of the silicon wafer needs to be treated to reduce the reflectivity of light. In the photovoltaic industry, the name of this process is called "texturing process". Because the quality of the texturing process directly affects the conversion efficiency of solar cells, the texturing process is a key process in the production of solar silicon wafers. In recent years, with the sharp reduction in the cost of diamond wire-cut silicon wafers, the ensuing problem is that the surface texturing process of diamond wire-cut polysilicon wafers does not match th...
