SOLLAR CELL AND FABRICATION METHOD THEREOF

摘要

PURPOSE: The solar battery having the photoelectric transduce rate in which the short-circuit current, the open circuit voltage, and the FF value better in comparison with the existing crystalline silicon solar cell and the solar battery and manufacturing method thereof excellent is offered through the process improvement to the production cost and the economic produce-time. CONSTITUTION: The anti-reflective layer is formed on the second electrical conduction semiconductor layer. The front electrode(106) partly passes through the anti-reflective layer and it is connected to the second electrical conduction semiconductor layer. The back side passivation layer(108) is formed in the back side of the first conductivity type semiconductor substrate.
