    • PROBLEM TO BE SOLVED: To provide: a method for preparing a CIGS film, by which a CIGS film excellent in conversion efficiency can be prepared at low cost and with good reproducibility even when a large area element is manufactured; and a method for manufacturing a CIGS solar cell, including the method for preparing a CIGS film.SOLUTION: The method for preparing a CIGS film includes: a lamination step of laminating a layer (A) including indium, gallium and selenium and a layer (B) including copper and selenium, in the order, on a substrate in a solid phase state; and a heating step of heating a laminate comprising the layer (A) and the layer (B) which are laminated, melting the compound of copper and selenium in the layer (B) to be changed in a liquid phase state, thereby diffusing copper in the layer (B) into the layer (A) to be grown in crystals, and obtaining a CIGS film.
    • 要解决的问题:提供:制备CIGS膜的方法,通过该方法可以以低成本且即使在制造大面积元件时具有良好的再现性来制备转化效率优异的CIGS膜; 以及CIGS太阳能电池的制造方法,包括CIGS膜的制造方法。 解决方案:制备CIGS膜的方法包括:层压步骤,其将包括铟,镓和硒的层(A)和包含铜和硒的层(B)依次层叠在基板上 固相状态; 以及加热层叠体的层叠体(A)和层(B)的层叠体的加热工序,使层(B)中的铜和硒化合物熔融成液相状态,使铜扩散 将层(B)进入层(A)中以生长晶体,并获得CIGS膜。 版权所有(C)2013,JPO&INPIT
