| 摘要 |
The present invention relates to a back contact solar cell module and a manufacturing method thereof. A battery cell which has a back substrate, a line, an anisotropic conducive adhesive having a conductive ball, an electrode, and a front substrate are successively stacked. The conductive ball is electrically connected to the electrode and the line. The spherical shape of the conductive ball fixed between the line and the electrode is changed into an oval shape. The diameter of the minor axis of the oval of the conductive ball is 25 to 95% of the diameter of the sphere. So, manufacturing costs can be reduced. |
