Ink-jetting printing head for super-thin grid solar cell

The invention discloses an ink-jetting printing head for a super-thin grid solar cell and aims at solving the problems that the width of a sintered thin grid line is difficult to lower than 50[mu]m, and the depth-width ratio is hard to control caused by the fact that the traditional screen printing electrode preparation technology is limited by the particle size of printing slurry and printing meshes. The ink-jetting printing head comprises a fixing seat and an ink-jetting head seat mounted at the bottom surface of the fixing seat; the ink-jetting head seat comprises multiple small ink chambers formed by micro-changed cross walls and micro-changed side walls; each small ink chamber is provided with an ink inlet hole and an ink jetting hole; the side of each small ink chamber is provided with first piezoelectric ceramic for adjusting the size of the ink jetting hole; second piezoelectric ceramic for driving ink to be jetted from the ink jetting hole is arranged above each small ink chamber. The preparation of super-thin grids is realized, a more precise electrode structure and a more excellent depth-width ratio are formed in comparison with those in the prior art, the shielding area is reduced and the photoelectric conversion efficiency is improved.
