Abstract
The utility model discloses a novel efficient high-resistance dense-grid solar monocrystalline silicon cell, which is characterized by having 65-75 grid lines, wherein the grid lines are 60-70 micrometers wide. The thin grid technique of the cell disclosed by the utility model reduces the width of the grid lines and increases the quantity of the grid lines on the premise that the light shading area is not increased, so the cell disclosed by the utility model collects more current, reduces the resistance of cells under serial connection, and increases the fill factor of cell.
Description
Technical field
The utility model relates to the new and effective solar energy single crystal silion cell sheet of the close grid of a kind of high resistant
Background technology
Along with the development of development of science and technology and photoelectron and communications industry, the figure and the effect of visible everywhere " silicon " in our life, crystal silicon solar energy battery is that to form industrialization over nearly 15 years the fastest.Solar energy single crystal silion cell sheet grating line radical is below 60 at present; The grid line width is more than 80 microns, and the electric current that therefore present solar energy single crystal silion cell sheet is collected is few, and battery sheet series resistance is high; Fill factor, curve factor is high, causes solar energy single crystal silion cell tablet quality to reduce.
The utility model content
The purpose of the utility model is the solar energy single crystal silion cell sheet that provides the close grid of a kind of high resistant new and effective, and this battery sheet can be collected more electric current, reduces the resistance of battery sheet series connection, improves the battery fill factor, curve factor.
To achieve these goals, the technical scheme of the utility model is: provide the close grid of a kind of high resistant new and effective solar energy single crystal silion cell sheet, wherein, the grid line radical of said this solar energy single crystal silion cell sheet is 65～75, and the grid line width is 60～70 μ m.
The utility model battery sheet can be collected more electric current, reduces the resistance of battery sheet series connection, improves the battery fill factor, curve factor.
Description of drawings
Fig. 1 is the structural representation of the new and effective solar energy single crystal silion cell sheet of the close grid of the utility model high resistant;
But the knowledge capital utility model is by 1 expression grid line from Fig. 1.
Embodiment
For the technology contents, the structural feature that specify the new and effective solar energy single crystal silion cell sheet of the close grid of the utility model high resistant, be described further below in conjunction with execution mode and conjunction with figs..
Solar energy single crystal silion cell sheet as shown in Figure 1, that the close grid of the utility model high resistant are new and effective, wherein, grid line 1 radical of said this solar energy single crystal silion cell sheet is 65～75, the grid line width is 60～70 μ m.The thin gate technique of the utility model battery sheet do not increase the shading area in advance down, reduce the width of grid line, increase the radical of grid line, so the utility model battery sheet collects more multiple current, reduce the resistance of battery sheet series connection, improve the fill factor, curve factor of battery.
The above disclosed preferred embodiment that is merely the utility model can not limit the interest field of the utility model certainly with this, so according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
