METHOD FOR PREPARING SILICA ANTI-REFLECTION COATING AND SILICON SOLAR CELL USING THE SAME

摘要

PURPOSE: A method for manufacturing a silica antireflection layer and a silicon solar cell using the same are provided to improve a short current density by decreasing a surface reflectivity of the solar cell. CONSTITUTION: Aqueous coating solutions including a silica precursor and a dopant precursor are coated on a semiconductor substrate(100). A dopant containing silica layer(200) is formed by a sol-gel method. The dopant containing silica layer is thermally processed under an air or oxygen containing gas atmosphere. An emitter layer(110) is formed by a p-n junction through the diffusion of a dopant. A spherical silica particle layer is formed on the semiconductor substrate.
