N-type bifacial interdigitated-back-contact (IBC) crystalline silicon solar cells were processed with screen-printed electrodes. The bifacial IBC cells resulted in a drastic decrease of the electrical shading loss at the finger region with decreasing pitch on the rear side. This loss was dominated by the width of the base region. In addition, …
