The following photographs show the first 30 minutes of the solution reaction for the chemical deposition of antimony sulfide thin films. This material is a p-type semiconductor. It is deposited as an amorphous source (Sb-S). The films have the necessary content to produce an orthorhombic lattice after heating above 250 ºC.
Antimony sulfide is used for the research of thin-film solar cells with the following configuration TCO/CdS/Absorber/BackContact. This film is achieved using the formula reported in the paper I publish during my Ph.D. program (With no AgNO3). Find it here.

For tips about deposition, feel free to write a comment!
|Initial deposition condition temperature near 10 ºC|
|The reaction of the Sb-S solution begins after 10 minutes.|
|The color of the reaction change completely at 30 minutes, this color will be maintained until the controlled precipitation finish.|
|After 3-4 hours of deposition, the films look good, there is adherence to the glass substrate and specular reflection in the surface.|
