Abstract

The invention relates to a constant temperature water bath apparatus for chemical plating and belongs to the technical field of solar batteries. The constant temperature water bath apparatus for the chemical plating is characterized in that an outer pipeline of the constant temperature water bath apparatus for the chemical plating is heated by using a mode that a multiple-in multiple-out circulating pipeline is filled with water; the whole tank body is segmented into a plurality of circulating cavities; each circulating cavity adopts a single-in and single-out form; a snake-like baffle is arranged in each circulating cavity; panels and separation boards of the circulating cavities are made of brass; and the surface of each panel is coated with a layer of polytetrafluoroethylene film. The constant temperature water bath apparatus disclosed by the invention has the advantages of high heating speed, good heat insulating effect, high heat conducting capacity, minimum temperature difference, uniform temperature of the whole heated surface, low possibility of deformation, high chemical corrosion resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of solar cells, in particular to a constant temperature water bath device for electroless plating. Background technique [0002] At present, CIGS solar cells have the characteristics of low production cost, low pollution, strong anti-irradiation ability, and good weak light performance. new thin-film solar cells". The preparation of CdS semiconductor thin film by chemical water bath method is an important part of CIGS solar cell preparation. It is required that the CdS semiconductor film can be completely coated on the large-area rough CIGS surface, that the CdS is dense without pinholes, and that the CdS film should be as thin as possible in order to reduce the series resistance. [0003] At present, most laboratories use a constant temperature water bath, and use a constant temperature chemical water bath deposition method to coat CdS thin films. By using the above-mentioned constant temperature device,...
