摘要： An interconnection piece (200) and a solar cell assembly, which relate to the technical field of photovoltaics and which ensure the normal interconnection of cell pieces, while also inhibiting the degree of deformation of back contact cells during welding. The interconnection piece (200) includes a flexible insulation substrate (210) and a plurality of structural welding strips (220) that are spaced apart on the flexible insulation substrate (210). Each structural welding strip (220) is provided with two welding portions and a connecting portion (221) located between the two welding portions. The connecting portions (221) are connected to two welding portions, respectively. At least part of each connecting portion (221) is located in the flexible insulation substrate (210), and the two welding portions extend out of the flexible insulation substrate (210). The solar cell assembly includes the interconnection piece (200) mentioned above.

摘要： A back contact solar cell assembly includes at least one cell string including multiple back contact solar cells and multiple electrically conducting lines. Each first electrodes includes first main grid lines and first fine grid lines. Each second electrodes includes second main grid lines and second fine grid lines. Each electrically conducting lines includes a first part conductively connecting the first main grid line of a first back contact solar cell, and a second part conductively connecting the second main grid lines of a neighboring second back contact solar cell. The first part is provided with at least one deformation cushioning component. At the shadow face of the first back contact solar cell, in the direction where the second fine grid lines are provided, the minimum distance between the projection of the deformation cushioning component and the second fine grid lines is greater than or equal to 0.3 mm.
