Copper indium gallium selenide thin -film solar cell

The utility model discloses a copper indium gallium selenide thin -film solar cell, this battery are upper electrode, window layer, transition layer, absorbed layer, mo electrode layer and flexible stainless steel substrate layer downwards from sensitive surface in proper order window layer surface is equipped with the magnesium fluoride antireflection layer, mo electrode layer and the middle silicon oxynitride barrier layer that is equipped with of flexible stainless steel substrate layer. The utility model discloses a flexible CIGS hull cell uses the stainless steel to replace using the CIGS hull cell of polyimide as the substrate as the substrate. For polyimide substrate, the stainless steel is as the substrate of battery, and the low price can reduce the manufacturing cost of battery. The stainless steel substrate is high temperature resistant in addition, is still having better mechanical stability and heat stability more than 600 DEG C, can greatly improve the horizontal homogeneity of CIGS film, haves
