摘要:
A solar cell and a method for manufacturing the same are discussed. The solar cell includes a substrate formed of an n-type crystalline semiconductor (110), an emitter region (121) of a p-type positioned at a first surface of the substrate, a first dielectric layer (191) positioned on a second surface opposite the first surface of the substrate, second dielectric layers (131, 192) respectively positioned on the emitter region (121) and the first dielectric layer (191), a third dielectric layer (132) positioned on the second dielectric layer (131) that is positioned on the emitter region, a first electrode (140) which is positioned on the first surface of the substrate and is connected to the emitter region, and a second electrode (150) which is positioned on the second surface of the substrate and is connected to the substrate. The emitter region (121) has a first textured surface including a plurality of first protrusions (11, 12), each of said first protrusions having a textured surface including a plurality of second protrusions (111, 112).
