BIFACIAL SOLAR CELL

摘要

Provided is a bifacial solar cell. The bifacial solar cell includes: a transparent substrate having a first side and a second side facing each other; a first transparent electrode disposed on the first side of the transparent substrate; a first light absorbing layer disposed on the first transparent electrode and exposing the first transparent electrode at one edge; a second transparent electrode disposed on the first light absorbing layer; a first metal electrode pad disposed on the exposed first transparent electrode; a third transparent electrode disposed below the second side of the transparent substrate; a second light absorbing layer disposed below the third transparent electrode and exposing the third transparent electrode in correspondence to the exposed first transparent electrode; a fourth transparent electrode disposed below the second light absorbing layer; and a second metal electrode pad disposed below the exposed third transparent electrode.
