Solar cell and manufacturing method therefor

Abstract

The present application provides implementations relating to a solar cell and a manufacturing method therefor, and pertains to the field of semiconductor device technologies. In an implementation, a solar cell includes a silicon substrate and a semiconductor layer. The silicon substrate includes a first surface and a second surface that are opposite to each other. The semiconductor layer is located on the first surface. The first semiconductor layer includes a first structural region and a second structural region. A crystallization degree of the first structural region is higher than a crystallization degree of the second structural region. The second structural region is closer to the first surface than the first structural region. The first semiconductor layer includes at least one of amorphous silicon, nanocrystalline silicon, or microcrystalline silicon.
