Abstract
Embodiments of the present disclosure provide a solar cell and a solar cell module. The solar cell includes a first region and a second region, and further includes a substrate having a first surface and a second surface; a tunneling layer covering the second surface; a first emitter formed on part of the tunneling layer in the first region; and a second emitter formed on part of the tunneling layer in the second region and on the first emitter, a conductivity type of the second emitter being different from a conductivity type of the first emitter. The solar cell further includes a first electrode configured to electrically connect with the first emitter by penetrating through the second emitter; and a second electrode formed in the second region and configured to electrically connect with the second emitter.
