Abstract
The utility model discloses a solar cell panel with annular PN junctions, which comprises a circular monocrystalline silicon wafer. P regions and N regions which are separated from each other are arranged from the center of the monocrystalline silicon wafer outwards. The P regions and N regions are annular regions. Engagement parts between the P regions and the N regions form PN junctions. Through arranging annular PN junctions on the solar cell panel, an electrode can be conveniently arranged on a backlight surface of the solar cell panel, thereby improving light transmittance of sun light at an irradiating surface of the solar cell panel, and furthermore improving photoelectric conversion efficiency of the solar cell panel.
Description
Technical field
The utility model relates to a kind of solar battery sheet that is provided with the ring-type PN junction.
Background technology
As everyone knows, the PN junction of up-down structure is arranged on existing solar battery sheet, on the PN junction surface of up-down structure, positive and negative electrode is set and is communicated with.Such structure makes the gate electrode line on the one side of sunlight incident block part sunlight, has reduced the light transmittance of solar battery sheet.Prior art is badly in need of a kind of solar battery sheet that can improve the solar battery sheet light transmittance.
The utility model content
The purpose of this utility model is to overcome the defect existed in prior art, and a kind of solar battery sheet of too high solar cell piece light transmittance is provided.
For achieving the above object, the technical solution of the utility model provides a kind of solar battery sheet that is provided with the ring-type PN junction, the described solar battery sheet that is provided with the ring-type PN junction comprises circular monocrystalline silicon piece, outwards be provided with P district and the N district of space along described monocrystalline silicon piece center, described P district and N district are annular region, and P district and convergence part, N district form PN junction.By annular PN junction is set on solar battery sheet, can easily electrode be arranged on to the shady face of solar battery sheet, improve the light transmittance of sunlight at the cell piece shadow surface, and then improve the electricity conversion of solar battery sheet.
As preferably, described P district is identical with N district ring body width.Such design is the further optimization to scheme.
As preferably, described P district and N district ring body width are 1 ~ 2mm.Such design is the further optimization to scheme.
Advantage of the present utility model and beneficial effect are: by annular PN junction is set on solar battery sheet, can easily electrode be arranged on to the shady face of solar battery sheet, improve the light transmittance of sunlight at the cell piece shadow surface, and then improve the electricity conversion of solar battery sheet.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1, monocrystalline silicon piece; 2, P district; 3, N district.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model more clearly is described, and can not limit protection range of the present utility model with this.
As shown in Figure 1, a kind of solar battery sheet that is provided with the ring-type PN junction, the described solar battery sheet that is provided with the ring-type PN junction comprises circular monocrystalline silicon piece 1, outwards be provided with P district 2 and the N district 3 of space along described monocrystalline silicon piece 1 center, described P district 2 and N district 3 are annular region, and P district 2 and 3 convergence parts, N district form PN junction.
Described P district 2 is identical with N district 3 ring body width.
Described P district 2 and N district 3 ring body width are 1 ~ 2mm.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
