Back contact solar cell assembly

A back contact solar cell module, wherein the back contact solar cell module comprises at least one cell string;

• the cell string comprises a plurality of back contact solar cells and a plurality of electrically conducting lines;
• a plurality of first electrodes and a plurality of second electrodes are provided at a shadow face of each of the back contact solar cells;
• a polarity of the first electrodes and a polarity of the second electrodes are different;
• each of the first electrodes comprises first main grid lines and first fine grid lines;
• each of the second electrodes comprises second main grid lines and second fine grid lines;
• each of the electrically conducting lines comprises a first part and a second part;
• the first part is configured for conductively connecting first main grid lines of a first back contact solar cell, and the second part is configured for conductively connecting second main grid lines of a neighboring second back contact solar cell;
• the first back contact solar cell is any one of the plurality of back contact solar cells;
• the first part is provided with at least one deformation cushioning component;
• and
• at a shadow face of the first back contact solar cell, in a direction where the second fine grid lines are provided, a minimum distance between a projection of the deformation cushioning component and the second fine grid lines is greater than or equal to 0.3 mm.
