    • A thin-film solar cell includes a cell having a transparent electrode layer, a photoelectric conversion layer, and a back electrode layer stacked on a transparent insulation substrate. A plurality of cells are connected in series to constitute a cell string. A bus bar is arranged on the back electrode layer of an end cell constituting the cell string. The thin-film solar cell has a photoelectric conversion layer on a series-connection direction end of the transparent electrode layer. In plan view, a series-connection direction end of the back electrode layer at an end of the cell string and the series-connection direction end of the transparent electrode layer at the end of the cell string do not overlap, while the bus bar and the transparent electrode layer at the end cell constituting the cell string overlap at least partially. A method of fabricating the thin-film solar cell is provided.
    • 薄膜太阳能电池包括具有透明电极层的单元,光电转换层和层叠在透明绝缘基板上的背面电极层。 多个单元串联连接以构成单元串。 在构成电池串的端电池的背面电极层上设置汇流条。 薄膜太阳能电池在透明电极层的串联方向端部具有光电转换层。 在平面图中,电池串端部的背面电极层的串联方向端和电池串端部的透明电极层的串联方向端部不重叠,而母线和 构成电池串的端电池的透明电极层至少部分重叠。 提供了制造薄膜太阳能电池的方法。
