采用电泳沉积法从Cu2ZnSnS4（CZTS）的胶体溶液中制备了一系列Zn离子部分置换Sn离子的自掺杂Cu2ZnSnS4（CZTS）薄膜。自掺杂的CZTS光电阴极比未掺杂的光电阴极产生更高的光电流，这归因于导带的上移和浅缺陷能级的形成。
A series of self-doped Cu2ZnSnS4 (CZTS) nanocrystal films with Sn ions partially replaced by Zn ions were prepared from their colloidal solutions by electrophoretic deposition. The self-doped CZTS photocathodes yielded higher photocurrents than the pristine one, which was ascribed to the upper shift in the conduction band and the formation of a shallow defect level.
