Abstract

The invention provides a method and system for drying a solar cell slurry. The method comprises: S1, a current cell piece is conveyed below a laser device; S2, location information of the cell piece is detected; and S3, according to the location information, the laser device is started to emit a laser beam to dry the cell piece. According to the drying method and system, the laser device is controlled to emit the laser beam to dry the cell piece. The drying furnace body of the linear laser device is made to be small; and thus compared with the existing laser device, the linear laser device with the small furnace body enables the occupied area to be reduced, so that the utilization rate of the plant is increased.

Description

technical field [0001] The invention relates to a method for manufacturing solar cells, in particular to a drying method and system for solar cell slurry. Background technique [0002] Photovoltaic power generation has become a clean energy that has developed rapidly in recent years. For heterojunction solar cells, the fabrication of electrodes is an indispensable process. [0003] In the battery production process of the prior art, the production of the electrode is mainly to form the required electrode pattern by screen printing the conductive paste, and then dry and sinter with hot air or infrared. [0004] The drying furnace and sintering furnace in the prior art are placed on the metal track in a single-piece or jammed manner. This kind of furnace body has a large volume, low heat absorption efficiency, high cost, and large power loss. Equipment Maintenance costs are high. Contents of the invention [0005] The object of the present invention is to provide a drying ...
