Abstract
The utility model discloses a front electrode structure of a crystalline silicon solar cell. The front electrode structure comprises a main grid line and a plurality of auxiliary grid lines, the main grid line is vertical to the auxiliary grid lines, and each auxiliary grid line is of a lattice line structure formed by a plurality of discontinuity points. The utility model designs a novel front electrode structure of a crystalline silicon solar cell, changes existing auxiliary grid lines of linear segment structures into points, and the plurality of points form an auxiliary grid line, thereby greatly saving the usage amount of silver paste, and reducing production cost.
Description
Technical field
The utility model relates to a kind of front electrode structure of crystal silicon solar cell sheet, belongs to field of solar energy.
Background technology
Conventional fossil fuel is approach exhaustion day by day, and in all sustainable energies, solar energy is undoubtedly a kind of cleaning, general and the most potential alternative energy source.At present, in all solar cells, crystal silicon solar energy battery is one of solar cell that obtains business promotion on a large scale, this is because silicon materials have very abundant reserves in the earth's crust, the solar cell that the while crystal silicon solar energy battery is compared other types has excellent electric property and mechanical performance, therefore, crystal silicon solar energy battery in the photovoltaic field in occupation of consequence.
The core component of traditional crystal-silicon solar cell is the battery sheet, and the front electrode structure of existing battery sheet mainly comprises 2 ~ 4 main grid lines that are parallel to each other, and many with the perpendicular secondary grid line of main grid line.Existing these main grid lines and secondary grid line all are straightway structures.This grid line generally all is to adopt conductive silver paste to constitute, and itself and silicon chip form ohmic contact.
Yet along with the quick increase in solar energy market, the consumption of conductive silver paste and price also rise thereupon, and this has brought very big cost pressure for the production of enterprise.
On the other hand, occur utilizing the electrode on nesa coating (as the ITO nesa coating) the replacement sensitive surface in the prior art, taken into account printing opacity and electric current collection, yet, because nesa coating needs and the battery sheet is electrically connected, therefore above-mentioned front electrode structure still needs.Therefore, how at the assurance nesa coating with when battery sheet good electrical is connected, further reduce the consumption of conductive silver paste, become the realistic problem of pendulum in face of the technician.
Summary of the invention
The utility model purpose provides a kind of front electrode structure of crystal silicon solar cell sheet.
For achieving the above object, the technical solution adopted in the utility model is: a kind of front electrode structure of crystal silicon solar cell sheet, comprise main grid line and a plurality of secondary grid lines, main grid line and the perpendicular setting of secondary grid line, the secondary grid line of described each bar is the dot matrix line structure for being made of a plurality of discontinuous points all.
Above, described secondary grid line is by the dot matrix line structure that a plurality of discontinuous points constitute, and the secondary grid line that is about to existing straightway structure becomes point one by one, constitutes a secondary grid line by plurality of points.Thereby saved silver-colored slurry consumption greatly.
In the technique scheme, described main grid line is provided with at least 1 hollow out section.Namely for each bar main grid line, at its original line segment a plurality of hollow out sections are set, with further minimizing silver slurry consumption.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1, the utility model design has obtained a kind of front electrode structure of new crystal silicon solar cell sheet, the secondary grid line of existing straightway structure is become point one by one, constitute a secondary grid line by plurality of points, thereby saved silver-colored slurry consumption greatly, reduced production cost.
2, the utility model is simple in structure, is convenient to preparation, and has good operability, practicality, is suitable for applying.
