Abstract
The present disclosure provides an interdigitated back contact cell and a manufacturing method thereof. The interdigitated back contact cell includes: a substrate including a front side and a back side, the front side being arranged opposite to the back side; where, along a first direction, first functional regions and second functional regions are alternately arranged on the back side of the substrate; an isolation region is arranged between every adjacent first functional region and second functional region; and the first emitter is spatially isolated from one adjacent second emitter by a corresponding isolation region; and the first diffusion layer is in contact with at least one adjacent second diffusion layer in a corresponding region of a corresponding isolation region. The interdigitated back contact cell provided by the present disclosure has a lower reverse breakdown voltage, a high component reliability, and a high cell efficiency.
