SOLAR CELL

摘要

A solar cell includes: a substrate having a front surface and a back surface; a dielectric layer disposed on the back surface and having at least two through holes to expose the back surface; at least two first electrode layers formed on the dielectric layer and respectively filling in the through holes to contact the substrate; at least one second electrode layer entirely formed on the dielectric layer and disposed between the first electrode layers; at least one space disposed on the dielectric layer; and at least one third electrode layer filled in the space to interconnect the second electrode layer and one of the first electrode layers.
