Abstract
The utility model provides a solar cell which comprises a silicon chip. A side surface of the silicon chip is provided with auxiliary grid lines which have a latticed structure. According to the utility model, the side surface of the silicon chip is provided with the auxiliary grid lines and the grid lines have a latticed structure. Thus, photogenerated charge also can be collected from different routes even if grid breakage happens to the solar cell. And power loss caused by failure in collection of photogenerated charge is avoided effectively.
Description
Technical field
The utility model relates to cell piece, more specifically, relates to a kind of solar battery sheet.
Background technology
Solar battery sheet is a kind of electrooptical device, and by silicon single crystal rod or polycrystal silicon ingot cutting preparation, the front electrode of this solar battery sheet can be collected photogenerated charge and the photogenerated charge of collecting is pooled together conventionally.Conventionally the front electrode of solar battery sheet is provided with the auxiliary grid line of tens of very thin metals, this auxiliary grid line be arranged in parallel conventionally, yet the drawback of this setup is once there is the situation of disconnected grid, photogenerated charge cannot be pooled to a place, thereby causes partial power's loss.
Utility model content
The utility model aims to provide a kind of solar battery sheet, to solve the problem that electric charge cannot collect when disconnected grid situation occurs solar battery sheet of prior art.
For solving the problems of the technologies described above, the utility model provides a kind of solar battery sheet, comprising: silicon chip, be provided with auxiliary grid line, and auxiliary grid line has fenestral fabric on the side of silicon chip.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
The utility model provides a kind of solar battery sheet, please refer to Fig. 1 to Fig. 5, and this solar battery sheet comprises: silicon chip 10, be provided with auxiliary grid line 20, and auxiliary grid line 20 has fenestral fabric on the side of silicon chip 10.
The utility model is provided with auxiliary grid line 20 on the side of silicon chip, and this auxiliary grid line 20 has network-like structure, and like this, even if the situation of disconnected grid occurs solar battery sheet, photogenerated charge also can collect from different routes.Therefore, the present invention has avoided cannot collecting because of photogenerated charge the power loss causing effectively.
Preferably, fenestral fabric comprises a plurality of compact arranged polygons.
Preferably, on the side of silicon chip 10, be also provided with the main grid line 30 crossing with auxiliary grid line 20.
Preferably, main grid line 30 is straight line.
Preferably, solar battery sheet comprises a plurality of main grid lines 30 that be arranged in parallel.
Preferably, polygon is hexagon.When polygon is arranged to hexagon, the material of supplementary gate is made in can be in the situation that not affecting charge integration at utmost low minimizing.
Preferably, auxiliary grid line 20 is made by metal material.
Preferably, the grid line width of the mid portion of auxiliary grid line 20 is greater than the grid line width of the marginal portion of auxiliary grid line 20.Generally, photogenerated charge is all pooled to the mid portion of auxiliary grid line 20, and therefore, the grid line that the grid line width of the mid portion of auxiliary grid line 20 is greater than auxiliary grid line 20 marginal portions is conducive to collecting of photogenerated charge.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
