The invention provides a laminated solar cell which comprises a plurality of laminated solar cell devices, each laminated solar cell device is sequentially provided with a bottom cell, a tunneling layer, a top cell, a top transparent conductive film layer and a metal grid line from bottom to top, and the metal grid lines are crossed grid lines or U-shaped grid lines. The crossed grid line comprises two groups of grid line structures which are arranged in a crossed manner, the two groups of grid line structures are integrated, each group of grid line structure comprises a plurality of grid lines which are arranged in parallel, and the U-shaped grid line is formed by a U-shaped coiled grid line. According to the technical scheme, the problems that in the prior art, a metal grid line of a traditional structure is poor in current collecting capacity and large in loss, and large-area and high-flux laminated solar cell industrialization transformation is difficult to achieve are solved. 本发明提供一种叠层太阳电池，所述叠层太阳电池包括若干叠层
