- •
Bulk Cu2ZnSnSe4 materials are directly produced by combustion synthesis under gas pressure or high gravity.
- •
Simultaneous densification is finished during synthesis to realize one-step preparation of dense samples.
- •
By In-doping the Cu2ZnSn0.9In0.1Se4 sample shows an enhanced ZT of 0.59 at 773 K.
