Abstract

The utility model relates to a novel polycrystalline silicon solar battery grid line structure. Thin grid lines which are vertical to the direction of a front-surface electrode are densely distributed on the front surface of a battery sheet, the thin grid lines which are parallel to the direction of the front-surface electrode are arranged at the two ends of the thin grid lines which are vertical to the direction of the electrode, and the thin grid lines which are parallel to the direction of the front-surface electrode are used for two-two connection of the thin grid lines vertical to the direction of the front-surface electrode. The novel polycrystalline silicon solar battery grid line structure can enhance the capability of collecting current by the thin grid lines of the battery sheet, reduce the light-blocking area of the thin grid lines, be conductive to upgrading the performances of the solar battery sheet, reduce the consumption of silver paste for screen printing and be conductive to reducing production cost.

Description

A kind of New Polycrystalline silicon solar cell grid line structure
Technical field
The utility model relates to polysilicon solar cell, particularly the grid line structure of polysilicon solar cell.
Background technology
Solar energy is a kind of regenerative resource of cleaning, and the solar cell that is the basis with the PN junction photovoltaic effect has fine application prospect.And the purpose of silk screen printing is the metal electrode of printed battery sheet; Its printing quality directly influences each item electrical performance indexes of battery sheet; Determined the product appearance specification of battery sheet simultaneously, the used material silver of silk screen printing slurry is the important component part of manufacture of solar cells cost.Along with the development of photovoltaic industry, to battery piece performance and cost of manufacture require increasingly highly, the graphic structure of front gate line has consequence in the research of efficient, low-cost solar cell with in producing.
The utility model content
The utility model aims to provide a kind of polycrystalline silicon solar grid line structure, improves the performance of battery sheet, reduces silk screen printing silver slurry consumption, reduces production costs.
A kind of New Polycrystalline silicon solar cell grid line structure; Battery sheet front is distributed with the thin grid line of vertical front side electrode direction; Perpendicular to the thin grid line of electrode direction two ends the thin grid line of parallel front electrode direction is being arranged, the thin grid line of parallel front electrode direction connects the thin grid line of vertical front side electrode direction to come in twos.
Preferably, the width of the thin grid line of said parallel front electrode direction is between 20um-120um.
The utility model has strengthened the collection of the thin grid line of battery sheet to electric current, and the shading area of thin grid line reduces to some extent, helps promoting the performance of solar battery sheet, reduces silk screen printing silver slurry consumption, helps reducing production costs.
Description of drawings
Shown in Figure 1 is the utility model structural representation.
Fig. 2 is an A portion enlarged drawing among Fig. 1.
Fig. 3 is a B portion enlarged drawing among Fig. 1.
Among the figure: 1-battery sheet, 2-front electrode, the thin grid line of 3-, the thin grid line of 4-.
Embodiment
Like Fig. 1,2, shown in 3; A kind of New Polycrystalline silicon solar cell of the utility model grid line structure; Battery sheet 1 front is distributed with the thin grid line 3 of vertical front side electrode 2 directions; Perpendicular to the thin grid line of electrode direction 3 two ends the thin grid line 4 of parallel front electrode direction is being arranged, the thin grid line 4 of parallel front electrode direction connects the thin grid line 3 of vertical front side electrode direction in twos and connects to come.
Preferably, the width of the thin grid line 4 of parallel front electrode direction is between 20um-120um.
The utility model has strengthened the collecting action of thin grid line to electric current, and the shading area of simultaneously thin grid line reduces to some extent, and the performance of favourable lifting battery sheet also reduces silk screen printing silver slurry consumption, helps reducing production costs.
Certainly; The utility model also can have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
