Solar cell and method for manufacturing the same

摘要

A solar cell and a method for manufacturing the same are discussed. The solar cell includes a substrate of a first conductive type, an emitter region of a second conductive type opposite the first conductive type positioned at the substrate, a first electrode which is positioned on the substrate and is connected to the emitter region, at least one second electrode which is positioned on the substrate and is connected to the substrate, and an aluminum oxide layer positioned on a front surface and a back surface of the substrate excluding areas of the substrate on which the first electrode and the at least one second electrode are formed.
