Figure 3From: A novel method for crystalline silicon solar cells with low contact resistance and antireflection coating by an oxidized Mg layerCarrier lifetimes of Si wafers with different Mg thicknesses and sintering steps. Mg200, thickness of Mg is 200 Å; Mg300, thickness of Mg is 300 Å; Mg400, thickness of Mg is 400 Å.Back to article page
