BC cells and BC solar cell stringer

Our REOO Company has developed a new type of Solar cell tabbing and string machine, specially used for BC solar cell stringer.

BC cells are also called interdigitated back contact cells. Since there is no grid line obstruction on the front of the BC structure, the light receiving area is increased and the incident light utilization rate is improved. Therefore, it always maintains an absolute advantage in conversion efficiency.

PERC, TOPCon, and HJT all improve the cell's ultimate conversion efficiency from the perspective of improving the passivation process and reducing electrical losses, and are competitive alternatives. The BC cell improves the ultimate conversion efficiency of the cell by increasing the illumination area and reducing optical loss, and there is no substitution relationship with other cells.

Moreover, the grid-free front of the BC cell is the "ultimate means" to reduce light shading. Not only is it difficult to be replaced by better processes, it can also be combined with other cells to form new XBC cells, that is, X cell + BC cell = XBC cell. That is to say, BC cells can be combined with PERC to form P-IBC cells, combined with TOPCon cells to form TBC cells, and combined with HJT cells to form HBC cells.
