Solar cell, screen printing plate structure, and photovoltaic module

Abstract

The present application discloses a solar cell, a screen printing plate structure, and a photovoltaic module. The solar cell includes a half-finished solar cell and a first electrode. The first electrode includes a plurality of first fingers and a plurality of first connecting portions. The plurality of first fingers are arranged at intervals along a first direction. Each of the first fingers extends along a second direction. The plurality of first connecting portions are arranged at intervals along the first direction. The first connecting portion is connected to the first finger. A portion of the first connecting portions are configured to be soldered with solder ribbons. A maximum height H1 of the first connecting portion satisfies: 4 μm ≤ H1 ≤ 10 μm. 20 25 28 73 70 24 D ec 2 02 5 2 0 2 5 2 8 7 3 7 0 2 4 D e c 2 0 2 5 2 / 9 FIG. 2 FIG. 3 2 / 9 10(10a) 40 21 C 21 22 22 X 23 23 Y H1 22 H2 21 Y FIG. 3 20 25 28 73 70 24 D ec 2 02 5 2 4 D e c 2 0 2 5 4 0 2 0 2 5 2 8 7 3 7 0 2 2 X 2 3 2 3 Y H 1 2 2 H 2 2 1 Y
