<p>Provided are a front gate line of a solar battery piece, and a solar battery piece. The front gate line comprises at least four main gate lines which are parallel to each other, wherein at least one main gate line among the main gate lines comprises a first connecting part (21) and a second connecting part (22), which are alternately connected end to end, and the width of the first connecting part (21) is greater than that of the second connecting part (22). By adding the number of the main gate lines in the front gate line to at least four, the series resistance of the solar battery piece is reduced; the metal slurry used for making a single main gate line is saved, and it is realized that the series resistance of the battery piece is reduced on the premise of a low production cost, thus improving the conversion efficiency of the battery piece.</p> |
