Copper zinc tin selenium solar cell device and preparing method thereof

Disclosed is a copper zinc tin selenium solar cell device based on a polyimide film and soda glass composite substrate. The device comprises glass, polyimide, a molybdenum back contact layer, a copper zinc tin selenium absorbing layer, a cadmium sulfide buffering layer, a transparent window layer high resistance eigen zinc oxide film, a transparent window layer low resistance eigen zinc oxide film and an aluminum electrode which form a stacked structure. A preparing method includes firstly coating the polyimide on the surface of the glass, solidifying and obtaining the polyimide film and soda glass composite substrate, preparing the films on the surface of the substrate sequentially, separating a cell body from the soda glass substrate after complete preparation, and obtaining the soft copper zinc tin selenium solar cell device based on the polyimide film and soda glass composite substrate. The device has the advantages that the grains of the copper zinc tin selenium film based on the polyimide ...
