Abstract
A solar cell includes a semiconducting substrate, a first emitter, an insulating layer, and a second emitter. The semiconducting substrate includes a first surface and a second surface, and includes a first region and a second region. The first region includes a first sub-region and a second sub-region. The first sub-region is in contact with the second region. The first direction is perpendicular to the thickness direction of the semiconducting substrate. The first emitter is disposed on the first surface and in the first region. The insulating layer is disposed on the first emitter and in the first sub-region. The second emitter is disposed on the first surface. The second emitter includes a first sub-emitter and a second sub-emitter. The first sub-emitter is located on the second region. The second sub-emitter is disposed on the insulating layer. Electrical conduction exists between the first emitter and the first sub-emitter.
