PURPOSE:To provide a solar cell of improved efficiency by using a simple process of making irregularities on its surface irrespective of whether its substrate is singlecrystal or polycrystalline. CONSTITUTION:Glass paste 2 is applied to form a pattern on a silicon substrate 1 and baked to obtain a glass layer. The glass layer is immersed in an alkaline solution to form irregularities on its surface. |
