Solar cell and manufacturing method therefor, and electric device

Abstract

A solar cell includes: a first electrode layer, an active layer, and a second electrode layer that are sequentially stacked, and a semi-encapsulation layer, where the semi-encapsulation layer includes a planar portion located between the active layer and the second electrode layer and an encapsulating portion at least partially located on at least one side surface of the active layer. The planar portion of the semi-encapsulation layer located between the active layer and the second electrode layer can suppress the migration of active ions in the active layer to the second electrode layer, and the encapsulating portion of the semi-encapsulation layer at least partially located on at least one side surface of the active layer can block external water and oxygen, and reduce the degradation of the active layer under the action of water and oxygen.
