Fabrication of Cu2ZnSn(S,Se)4 (CZTSSe) absorber films based on solid-phase synthesis and blade coating processes

- Pure CZTS nano-crystalline have been prepared based on solid-phase synthesis.
- A simple and modified doctor blade process followed by a selenization technique was utilized to fabricate CZTSSe absorber films.
- Comparative studies on the properties of CZTS and CZTSSe absorber films have been investigated.
- The band gap of CZTSSe absorber films was determined to be 1.26 eV.
