Bifacial solar cell and method for producing

Disclosed is a method for processing a silicon wafer to a bifacial solar cell having a boron-doped silicon layer and an antireflection layer of silicon nitride on the back. To form the back serving as a doping source boron-containing layer is deposited directly on the silicon wafer. In this, an SiO A heat treatment ensures that boron diffuses from the boron-containing layer in the silicon wafer. is further described a manufacturable according to this method bifacial solar cell.
