- •
We can suppress the tin loss by adding SnS powder during selenization.
- •
We modify the S/(S+Se) ratio by changing the amount of SnS powder.
- •
The formation of Mo(S,Se)2 is dramatically suppressed by adding SnS powder.
- •
We propose SnS reacts with Se to form SnSe and releases S vapor during selenization.
- •
The efficiency is improved from 3.97% to 7.35% by adding SnS powder.
