摘要
We have developed flexible Cu(In,Ga)Se-2 (CIGS) solar cells on stainless-steel foils. The CIGS films deposited by an in-line evaporation system have strong adhesion to Mo films. The phases of CIGS films on the stainless-steel foil was almost the same as that on the glass, but the grain size of CIGS films on the Mo/ stainless-steel foils are smaller than those of the films on the glass. We also examined insulating layers and resulted in that the insulating layers had no influence on the formation of CIGS and the cell performance. Furthermore we fabricated CIGS solar cells with sodium compound layers to improve efficiency and achieved an efficiency of 14.3% with the stainless-steel foils.
