Background technology
In current energy starved situation, solar energy attracts wide attention as a kind of renewable resource.Exploitation for solar energy have become the big event that new forms of energy were asked for and utilized in countries in the world, and are especially now like a raging fire to the research of solar power generation.
Existing standard-sized solar battery sheet is generally 5 cun or 6 cun, a plurality of solar battery sheets need to be electrically connected to when forming solar module.At present, the photoelectric conversion efficiency of monocrystalline silicon and polysilicon solar cell is substantially more than 15%, how exceeding under the prerequisite of appending the solar battery sheet manufacturing cost, the power that improves by a relatively large margin solar cell is present photovoltaic those skilled in the art institute outline.
In addition, because solar cell is more fragile, therefore in producing, transporting or be assembled into the process of solar module, all can cause breakage.In case breakage occurs, the full wafer solar cell just will be scrapped.This can cause great waste, how effectively to utilize damaged cell piece, enables twice laid, is also the difficult problem that person skilled faces.
The utility model content
The utility model provides a kind of solar module, uses the solar module of a plurality of solar battery sheet section compositions, has effectively improved the power utilization of solar battery sheet, has reduced the electrical current heat loss in the solar components.
An aspect according to this practicality, a kind of solar module is provided, it is characterized in that, described solar module comprises a plurality of solar battery sheet sections, described solar battery sheet section is adopted and is electrically connected to, and described solar battery sheet section is formed by described solar battery sheet cutting.
According to an embodiment of the present utility model, it is characterized in that, described solar battery sheet section is carried out the decile cutting by described solar battery sheet and is formed.
According to another embodiment of the present utility model, it is characterized in that, the section of described solar battery sheet is undertaken not by described solar battery sheet that the decile cutting forms.
According to another embodiment of the present utility model, it is characterized in that, described solar battery sheet section is to form along the direction cutting perpendicular to described solar battery sheet main grid line.
According to another embodiment of the present utility model, it is characterized in that, described solar battery sheet section is described solar battery sheet to be carried out straight cuts form.
According to another embodiment of the present utility model, it is characterized in that, described solar battery sheet section is described solar battery sheet to be carried out the non-rectilinear cutting form.
According to another embodiment of the present utility model, it is characterized in that, described solar module is formed by solar battery sheet section series connection.
According to another embodiment of the present utility model, it is characterized in that, the material of described formation solar battery sheet is any one in polysilicon, monocrystalline silicon, quasi-monocrystalline silicon.
According to another embodiment of the present utility model, it is characterized in that, the area of described solar battery sheet section is 5cm
2~ 74cm
