| titleOfInvention | Synthetic method for Cu2ZnSnS4 photosensitive thin-film material |
| abstract | A synthetic method for Cu2ZnSnS4 photosensitive thin-film material is characterized by comprising the following steps: dissolving blue vitriol crystal, white vitriol crystal and dihydrate tin sulphate crystal in alcohol organic solvent to obtain solution A with the molarity of zinc sulfate of 5-15 millimole/L; placing the solution A in a flask and heating up to the temperature of 170-210 DEG C, and inletting argon into the solution A simultaneously while heating; after the heating, dropwise adding sodium sulphide solution into the solution A, still standing and natural cooling to obtain solution B generating Cu2ZnSnS4 nano-particles; heating the solution B up to the temperature of 80-120 DEG C, dropwise adding dispersing agent, still standing and cooling, wherein the obtained solution B is divided into an upper layer and a lower layer, and the upper layer black liquid is Cu2ZnSnS4 nano solution, and manufacturing the separated black liquid of Cu2ZnSnS4 nano solution into thin films. |
