MULTIJUNCTION SOLAR CELL AND A METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: A multi-junction solar cell and a manufacturing method thereof are provided to prevent the reduction of a lifetime of a carrier by bonding a substrate after grid matched materials are grown on heterogeneous substrates. CONSTITUTION: A first solar cell layer(12) is deposited or grown on a first base substrate. A second base substrate(20) is made of materials which are different from the first base substrate. A second solar cell layer(22) is deposited or grown on the second base substrate. A bonding layer(30) bonds an ohmic layer formed on the first solar cell layer or the first base layer to an ohmic layer formed on the second solar cell layer or the second base layer.
