Abstract

The invention relates to a jet printing device which is suitable for a manufacturing process of a dye-sensitized solar cell. The jet printing device at least comprises a platform mechanism used for bearing a conductive substrate and at least two groups of jet printing head assemblies which are used for containing a water-solubility semiconductor solvent and a dye solvent respectively. The platform mechanism for bearing the conductive substrate conducts displacement relative to at least two groups of jet printing head assemblies to conduct jet printing operation of the water-solubility semiconductor solvent and the dye solvent sequentially on the surface of the conductive substrate. The thickness of the water-solubility semiconductor solvent and the dye solvent printed on the surface of the conductive substrate is arranged between 0.1 mum and 100 mum.

Description

technical field [0001] The invention relates to a jet printing device, especially a jet printing device suitable for dye-sensitized solar cell manufacturing process. Background technique [0002] In order to solve the global energy crisis and reduce environmental pollution, solar cells that can directly convert solar radiation energy into electrical energy have been actively innovated and developed in recent years. Among them, dye-sensitized solar cells (Dye Sensitized Solar Cell, DSSC for short) are The third generation of organic solar cells has the characteristics of low cost and energy conversion efficiency similar to silicon thin film solar cells. Compared with traditional single (poly) crystalline silicon or amorphous silicon solar cells, dye-sensitized solar cells have low raw material cost, easy manufacturing process and simple process equipment, which can effectively reduce the cost of solar cell power generation. The promotion of commercialization has considerable...
