SOLAR CELL

摘要

A solar cell is disclosed, which includes: a semiconductor substrate, an anti-reflective layer, a passivation layer, a back electrode and back bus bar. The semiconductor substrate has a first surface and a second surface. The anti-reflective layer is disposed on the first surface. The back electrode is a continuous electrode or a flat electrode overlapping the whole back side of the solar cell. The continuous electrode or the flat electrode connects to the semiconductor substrate through a continuous opening. In another embodiment, the continuous electrode is passing through the passivation layer directly and connecting to the semiconductor substrate. That is, the solar cell includes a continuous opening or a continuous electrode.
