N Type IBC Solar Cell

【Product description】

In the interdigitated back contact (IBC) cell structure the emitter and contact are both on the back side of the wafer which allows independent optimization of the front surface for optical properties and back surface for electronic properties of the emitter and contacts.

IBC solar cells have shown outstanding performance either on concentration or one-sun illumination. The advantages of this design include that there is no contact grid shading at the sunward side and potentially low substrate cost due to a thin device design. Moreover, the module assembling costs are potentially lower as both contacts are on the rear. Finally, the solar cells can be placed closer together in the module because there is no need for a space between the cells.

Interdigitated Back Contact(IBC) solar cell is the key solution to the challenge of increasing cell efficiency and lowering the cost of solar cell manufacturing in solar cell industries.
