A: The manufacturing method 600 is similar to the manufacturing method 1 〇〇, but not = 2 7 conversion layer cutting step 640 is more than a total of _ electricity; 230 can pass through the through opening 59 、, when the layer 220 is on the 'wood electrical connection The common substrate portion 21〇ec 201106489 is formed in the common conversion portion by the through-opening π 590. Therefore, when the crucible 5 is formed by 90 electric power, the electrode portion can be connected to the common substrate portion through the through opening. 21〇^ Since the common electrode portion 23 of the photovoltaic cell module is electrically connected to the common substrate portion 21Ge, the output of the battery module is no longer limited by the common conversion portion 22Ge, and the photovoltaic cell module Group 5()() can be larger than the photovoltaic cell module 2〇〇.

Please refer to 7th and 8th, 7th, and 7th is a schematic cross-sectional structure diagram of a photovoltaic cell module 7A according to an embodiment of the present invention, and FIG. 8 is a manufacturing method of the photovoltaic cell module 700. 8〇〇 Process diagram. The manufacturing method 800 is similar to the manufacturing method 6〇〇, but differs in that the electrode layer cutting step 86 of the manufacturing method 800 does not cut out the electrode portions 230c and 230d' so that a larger piece of the common electrode 73〇e' can be produced and shared The electrode 730e is electrically connected to the common substrate portion 21〇e through the conversion layer isolation spaces 222b and 222c. In addition, it is worth mentioning that in the manufacturing method 8A, a conversion layer removing step may be added between the photovoltaic conversion layer cutting step 440 and the electrode layer forming step 150 to remove the common conversion layer 220e and form a depressed portion. In the subsequent electrode layer forming step 150, the electrode material is filled in the depressed portion, so that the conductive effect between the common electrode portion 730e and the common electrode portion 730e is more excellent. Referring to FIG. 9 and FIG. 10 together, FIG. 9 is a cross-sectional structural diagram of a photovoltaic cell module 900 according to an embodiment of the present invention, and a photocell photovoltaic module is shown in FIG. The flow chart of the photovoltaic cell module ^法咖 The electrode becomes a thin layer of the -d solid photovoltaic cell module, which is used in the early '970' to connect the two photovoltaic cell modules 92. And the common electrode portion %. And the polarity of the wires μ and 2 and the polarity of the charge output by the wire 25G (4). The outlet cell unit 970 is constructed by combining two photovoltaic cell modules. Therefore, the manufacturing method of the photovoltaic cell module is just the second type: the manufacturing method of the volt battery module 200. Different: In the substrate cutting step 1020, two battery cell substrate portions and a common substrate portion 91 are cut out. In the 』==:!°4°, two common conversion sections are cut out into two common conversion sections 92G; in the electrode layer cutting unit 辕', two common electrode sections 230e are cut out, and four batteries are early 70 conversion sections. And a common electrode portion 930. An electric ^ implementation H 'Because a photovoltaic cell module 2〇0 contains two early battery modules _ contains four battery cells in parallel with each other' so in the photovoltaic cell module 9〇〇, even if there are three bad' The photovoltaic module _ can still supply power to the external device normally.
