Definitions
- the present invention relates to a solar cell module.
- the power generation cost of solar power generation is still high, and further reduction in power generation cost is necessary for the spread of solar power generation.
- the substrate occupies most of the costs.
- wafer prices have risen due to a shortage of silicon (Si) raw materials for solar cells, and solar cell manufacturers have addressed this problem by using thinner wafers.
- Si silicon
- the formation of the BSF layer using the Al paste described above is also a factor that hinders the thinning of the wafer. This is due to the difference in thermal expansion coefficient between Al and Si at the time of firing, causing the problem that the warpage of the cell increases as the wafer becomes thinner, and cracks occur during modularization. It is.
- back electrodes for solar cells of this type a point contact where electrodes are connected to the back surface of the wafer in a point manner, and a comb-shaped electrode where electrodes are provided in a comb shape on the back surface of the wafer.
- Comb electrodes are considered to be mainstream because of their high nature.
- the power generation cost is explained from the viewpoint of the reliability of the solar cell module. For example, assuming that the solar cell module output is constant, if the lifetime of the solar cell module is extended from 10 years to 20 years, the power generation cost is halved. Thus, the power generation cost can also be reduced by improving the long-term reliability of the solar cell module.
- a-Si amorphous silicon
- individual solar cells are interconnected and modularized after the fabrication of the solar cells. Since the voltage of one solar cell is as low as about 0.5V to 1V, a plurality of solar cells are formed with a flat conductive wire called a tab (or ribbon) or a metal foil called an interconnector so that a high voltage can be obtained. Cells are connected in series.
- a terrestrial solar cell uses a tab because the current per solar cell is large, and the stress applied to this tab has a great influence on the long-term reliability of the solar cell module. That is, since the solar cell module is installed outdoors, the temperature of the solar cell module changes cyclically, and the tab repeatedly expands and contracts. This causes the tab to undergo metal fatigue and eventually break. Therefore, alleviating the stress on the tab is effective for improving the long-term reliability of the solar cell module.
- Patent Document 1 a technique for providing play in the tab by devising a connection portion between the solar battery cell and the tab
- Patent Document 2 a technique for using a unique shaped interconnector
- Patent Document 3 A technique using a three-dimensionally bent interconnector (see, for example, Patent Document 3) has been proposed.
- Patent Document 2 and Patent Document 3 cells are connected using an interconnector.
- the ground solar cell has a large extraction current, when an interconnector is used, the resistance increases and the resistance loss increases. For this reason, it is difficult to apply the interconnector in the ground solar cell from the viewpoint of the characteristics of the solar cell.
- the present invention has been made in view of the above, and an object thereof is to obtain a solar cell module excellent in long-term reliability and power generation cost.
- the solar cell module according to the present invention is the first in which the in-plane directions are substantially the same and adjacent in the first direction and have connection electrodes on the light receiving surface and the back surface.
- a solar cell module in which one solar cell and a second solar cell are electrically connected in series by a connection tab made of a conductive material, the connection electrode on the back surface of the first solar cell serving as the connection tab And the second solar cell while being electrically connected to the connection electrode on the light-receiving surface of the second solar cell and the first connection tab extending to the back surface side of the second solar cell.
- a second connection tab having a folded portion that extends and bends on the first solar cell side of the cell to the back surface side of the second solar cell.
- the tab and the second connection tab are in an overlapping region where the first connection tab and the second connection tab overlap on the back surface side of the second solar battery cell, and in the first direction than the overlapping region. Are connected in a narrow connection area.
- connection tab is increased, and as a result, the stress on the connection tab due to the cyclic change of the module temperature is relieved, and the breakage of the connection tab due to the thermal stress can be prevented. As a result, it is possible to improve the performance and reduce the power generation cost.
