The scientists looked for a way to bypass these flaws and produce the best quality CZTSSe (copper, zinc, tin, sulfur, and selenium) thin films. They came up with the ingenious solution of toying with the film’s annealing profile.
They found that the longer the annealing time and the higher the annealing temperature, the lesser the electricity loss. Once they came up with this solution, they had to deal with the fact that high annealing temperatures cause the properties of the CZTSSe thin film to decompose over time.
To bypass this next problem, the team used a special “liquid-assisted method” that prevented the CZTSSe thin film to change its properties.
