METHOD FOR PRODUCING CIGS FILM, AND METHOD FOR MANUFACTURING CIGS SOLAR CELL USING SAME |
摘要 |
A CIGS film production method is provided which ensures that a CIGS film having a higher conversion efficiency can be produced at lower costs at higher reproducibility even for production of a large-area device. A CIGS solar cell production method is also provided for producing a CIGS solar cell including the CIGS film. The CIGS film production method includes: a stacking step of stacking a layer (A) containing indium, gallium and selenium and a layer (B) containing copper and selenium in a solid phase in this order over a substrate; and a heating step of heating a stacked structure including the layer (A) and the layer (B) to melt a compound of copper and selenium of the layer (B) into a liquid phase to thereby diffuse copper from the layer (B) into the layer (A) to permit crystal growth to provide a CIGS film. |
