摘要
The present invention relates to a method for manufacturing a CZTS-based thin-film solar cell light absorption layer, and to a CZTS-based thin-film solar cell light-absorbing layer prepared therefrom, and specifically, i) forming a first electrode layer on a substrate, ii) the first 1 forming a zinc (Zn) precursor layer on the electrode layer, iii) forming a copper (Cu) precursor layer on the zinc (Zn) precursor layer, iv) tin (Cu) on the copper (Cu) precursor layer Sn) forming a precursor layer, and v) forming an alkali metal compound layer, comprising: forming a precursor layer comprising the step of forming the alkali metal compound layer, the first electrode layer and zinc A first alkali metal compound layer formed between the (Zn) precursor layer, a second alkali metal compound layer formed between the zinc (Zn) precursor layer and the copper (Cu) precursor layer, the copper (Cu) precursor layer and tin ( Sn) relates to a method for manufacturing a light absorption layer of a CZTS-based thin film solar cell, characterized in that at least two of the third alkali metal compound layer formed between the precursor layers is formed.
