Abstract: A solar cell unit comprises a cell. The cell includes a cell substrate and a secondary grid line disposed on a front surface of the cell substrate. The solar cell unit also comprises a conductive wire intersecting and welded with the secondary grid line. The secondary grid line has a width in a welding position with the conductive wire greater than a width thereof in a non-welding position.

Abstract: The disclosure discloses a photovoltaic cell assembly, a photovoltaic cell array, and a solar cell assembly. The photovoltaic cell assembly includes: a plurality of photovoltaic cells arranged sequentially along a longitudinal direction, and at least one conductive band, where each photovoltaic cell includes a silicon wafer, a front conductive member disposed on a front surface of the silicon wafer, two electrodes disposed on a back surface of the silicon wafer, and a side conductive member that is disposed on a side surface of the silicon wafer and that is electrically connected between the front conductive member and one electrode, where the two electrodes extend along a transverse direction and are distributed at an interval in the longitudinal direction; and the conductive band has an extension direction the same as that of the electrode, and is electrically connected to two electrodes that are close to each other and that are respectively located on two neighboring photovoltaic cells, so that the two neighboring photovoltaic cells are connected in series or connected in parallel.
