METHOD FOR MANUFACTURING SOLAR CELL

摘要

PURPOSE: A method for manufacturing a solar cell is provided to form a transparent electrode and an intrinsic layer with different electric properties by a sputtering process using one target. CONSTITUTION: A bottom electrode is formed on a substrate. A light absorbing layer(30) is formed on the bottom electrode. A buffer layer(40) is formed on the light absorbing layer. A window layer(70) including an intrinsic layer and a transparent electrode with different electric properties is formed on the buffer layer. The intrinsic layer and the transparent electrode are formed by a sputtering process using one target made of metal oxide doped with metal impurities.
