    摘要： A photovoltaic module includes a cell string, transparent insulated flexible protectors, a front adhesive film, a back adhesive film, a first plate, a second plate. The cell string includes multiple cells. Adjacent cells are connected in series through multiple spaced welding ribbons. The area on the surface of each cell without the welding ribbons is a mounting portion. Adjacent cells are staggered vertically. The protector is arranged on the front or back side of each cell. The protector includes a first protective portion connected to the surface of the mounting portion, and a thickness of the first protective portion is not less than thicknesses of the welding ribbons. The front adhesive film and the back adhesive film are respectively connected to the front side and back side of the cell. The first plate and the second plate are connected to the front adhesive film and the back adhesive film, respectively.

    摘要： Disclosed are a shingled cell, a cell unit, and a shingled photovoltaic assembly. The cell unit includes a cell. The front side of the cell includes a plurality of parallel front-side fine grid lines. The back side of the cell includes a plurality of parallel back-side fine grid lines and a front-side connection line. The front-side connection line is a continuous or non-continuous line segment. The front-side connection line is arranged on at least one side of the cell. The front-side connection line is connected to the ends of all the front-side fine grid lines on the same side. The front-side connection line is such configured that when two cell units are overlapped along the extension direction of the front-side fine grid lines, the front-side connection line of the lower cell unit contacts each of the back-side fine grid lines of the upper cell unit.

    摘要： A half-cell assembly includes an integrated junction box and multiple cell string sets connected in series sequentially. Each cell string set includes multiple cell strings connected in parallel, and each cell string includes multiple half-cells connected in series sequentially. The multiple cell string sets are arranged along a first preset direction. In each cell string set, the multiple cell strings are arranged along the first preset direction. In each cell string, the multiple half-cells are arranged along a second preset direction. One of the first preset direction and the second preset direction is the long side direction of the half-cell, and the other is the short side direction of the half-cell. The integrated junction box and the multiple cell string sets are arranged along the second preset direction. The multiple cell string sets are connected in parallel with diodes of the integrated junction box.
