Embodiment Construction

[0034] The present invention will be described in detail below in conjunction with the drawings and specific embodiments of the specification.

[0035] At present, the main application formats for printing are relief, offset, and intaglio. The existing common intaglio printing is characterized by concave parts of the graphics and text, so that the layout is completely immersed in the printing material, and then the excess printing material is scraped off with a squeegee to remove the remaining concave The method of transferring the lower part of the printed material to the printed matter is gravure printing. This solution uses conductive silver paste as a printing material for printing on solar cells. The printed matter has a three-dimensional effect, and the small lines can be printed clearly, so that various plates can be freely and widely selected and used.

[0036] Such as figure 1 As shown, this solution establishes a system for screen printing to print the substrate 1 of th...

Abstract

The invention discloses a system used for solar battery cell printing and a printing method, and belongs to the field of solar photovoltaic manufacturing. Aimed at for solving the problems that in theprior art, printing of a solar battery cell is up and down, printing uniformity is poor, and printing quality and the transfer effect of a solar substrate are poor, the invention provides the systemused for solar battery cell printing and the printing method. The system comprises a transfer medium and further comprises an unwinding mechanism, an intaglio printing mechanism, a transfer mechanismand a winding mechanism which are arranged in sequence, transfer media enter the intaglio printing mechanism sequentially through the unwinding mechanism to print patterns, then, the transfer media enter the transfer mechanism to transfer the patterns to the substrate, and the transfer media enter the winding mechanism finally. Through tension control, laser transfer, slab transfer or round rollertransfer, printing uniformity can be achieved, the printing effect is good, and the transfer effect is excellent.

Description

Technical field [0001] The invention relates to the field of solar photovoltaic manufacturing, and more specifically, to a system and a printing method for solar cell printing. Background technique [0002] With the widespread application of solar cell technology, the printing quality of silicon wafers for solar cells has become a key to ensuring the conversion efficiency of solar cells. The traditional printing squeegee uses a linear feed mechanism (such as a screw feed mechanism, a linear sliding table, etc. to push the squeegee) for grid line printing, which has slow printing speed, low productivity, high fragmentation rate, and uneven grid line printing. There are also related printing methods in the prior art to improve the solar cell printing field. [0003] For example, a Chinese patent application, application number 201210375527.3, published on April 10, 2013, discloses a film transfer device in which a film accumulation device is arranged above the vertical direction of ...
