Abstract

The utility model discloses a grid line manufacturing template of solar cells, which comprises a knitted meshed grid metal supporting frame, an upper photosensitive adhesive layer, a lower photosensitive adhesive layer and a metal frame, wherein the upper photosensitive adhesive layer and the lower photosensitive adhesive layer are covered on the supporting frame. Main grid line grooves and auxiliary grid line grooves are arranged at the positions of the upper photosensitive adhesive layer and the lower photosensitive adhesive layer corresponding to the positions of a main grid line and an auxiliary grid line required by the solar cells. Rhombic photosensitive adhesive layers are arranged on each main grid line at intervals and are in the same level with the upper photosensitive adhesive layer and the lower photosensitive adhesive layer, and the interval spaces are larger than the width of a testing probe. The photosensitive adhesive layers are covered on some positions of the main grid line groove with no effect on the conductivity, the amount of silver paste is greatly saved during printing, the manufacturing cost of the solar cells is lowered, and market competitiveness is improved.

Description

A kind of solar cell grid line is made template
Technical field
The utility model relates to a kind of solar cell grid line and makes template.
Background technology
Be distributed with a large amount of auxilliary grid lines and three main grid lines on the solar battery sheet, the electric current that flows through on the auxilliary grid line is flowed on the main grid line, flowing to the band that confluxes again after, guide to the battery outer end by terminal box.Auxilliary grid line on the solar battery sheet and main grid line are made template by the solar cell grid line silver slurry are printed onto on the solar battery sheet, existing solar cell grid line make template be will braiding grid metal supporting frames with holes be embedded in and form main body in the photosensitive layer, again after blocking the position that does not need to expose with lighttight pattern on the main body, photographic exposure, again unexposed photoresists water is washed out, thereby form main grid wire casing and auxilliary grid line groove, be placed on the solar battery sheet, with silver slurry press printing silver slurry, silver slurry to solar battery sheet, is printed to auxilliary grid line and main grid line by the main grid wire casing on the template and auxilliary grid line concentrated flow on solar battery sheet.In order to guarantee the power of solar battery sheet, the width of the main grid wire casing on the template there is certain requirement, the main grid wire casing even thickness on the existing template.The required silver slurry of auxilliary grid line of printing and main grid line costs an arm and a leg, and the price of all kinds silver slurry is all more than 8000 yuan/kilogram, and the consumption of every battery sheet front side silver paste accounts for 40% of solar battery sheet cost of material about the 0.24-0.28 gram now.If can reduce the production cost of solar cell undoubtedly guaranteeing to reduce silver slurry use amount significantly by changing formwork structure under the prerequisite that power does not reduce after the component package, improve the market competitiveness.
The utility model content
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provides a kind of solar cell grid line to make template, uses auxilliary grid line and main grid line on this template construct solar battery sheet, saves silver slurry consumption.
For achieving the above object, technical solution of the present utility model is: a kind of solar cell grid line is made template, and it comprises the grid metal supporting frames with holes of braiding, covers upper and lower photosensitive layer and metal edge frame on the bracing frame; Upper and lower photosensitive layer is having main grid wire casing and auxilliary grid line groove with the main grid line of battery sheet requirement and the corresponding position, position of auxilliary grid line, it is characterized in that: be intervally distributed with the rhombus photosensitive layer that flushes with upper and lower photosensitive layer on every main grid wire casing, spacing distance is greater than the width of test probe.
Spacing distance between the above-mentioned described rhombus photosensitive layer is not less than 3.7mm.
The length of above-mentioned described rhombus photosensitive layer is not more than 15mm, and the wideest position of rhombus and the distance of main grid wire casing wall are not less than 0.2mm, to guarantee the power after the battery sheet encapsulates.
The utility model has been added a cover photosensitive layer in some positions of main grid wire casing on the basis that does not influence electric conductivity, saved the consumption of silver-colored slurry during printing greatly, has reduced the production cost of solar cell, has improved the market competitiveness.With the main grid line width is that 1.5mm, main grid number of lines are that 3, auxilliary grid line width are that 90um, auxilliary grid number of lines are that 68, efficient are that 156 * 156mm solar battery sheet of 16.8% is an example, battery sheet gross area 24336mm 2, by the grid line area occupied 1774.41mm of prior art making 2, every grid line silver slurry weight 0.25g, 4.087 watts of power; Every grid line silver slurry weight by the utility model fabrication techniques reduces 0.028g, amounts to 0.224 yuan of RMB.Because the photosensitive layer of adding a cover in some positions of main grid wire casing does not influence assembly welding and electric current collection, so power do not have excess loss substantially, can ignore.Along with development of technology, if can invent out transparent welding, the economic benefit of technological improvement of the present utility model can be more obvious in the future.
