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. Application 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.
