摘要： The present invention relates to a photovoltaic cell module and a manufacturing method thereof. The photovoltaic cell module includes n1 photovoltaic generating groups, each photovoltaic generating group includes n2 photovoltaic cell units arranged in a second direction, the photovoltaic cell units within each photovoltaic generating group are positioned between two photovoltaic conductive strips, the two photovoltaic conductive strips have discontinuous points, which are used to change the series-parallel connection between the photovoltaic cell units within the photovoltaic generating group. The manufacturing method of module includes the steps of firstly making the photovoltaic cell unit, then typesetting the photovoltaic cell unit, the photovoltaic conductive strip, the front panel and the rear panel, next making a photovoltaic cell module through lamination. The beneficial effect of the present invention is that adjusting the positions of discontinuous points and the upward-downward position and forward-backward direction of the photovoltaic cell string during type-setting enables the electrical performance parameters and series-parallel setting of the photovoltaic module to ease adjusting, so as to achieve flexible manufacturing. The photovoltaic cell strings are interconnected with each other through metallic foil conductive trips, especially through flexible flat cables, so that it is possible to make low-costs and flexible foldability a reality.
