Study of thermal and post- deposition treatments in Sb2(S, Se)3 thin film grown by hydrothermal processes

Abstract

[Excerpt] Thin film technology has stood out by trying to overcome limitations related to Si technology, including the high energy payback times, low industrial production rates, and significant initial investment values associated with production facilities. It provides advantages such as monolithic integration, lower energy processes, and reduced material requirements. The antimony chalcogenides Sb2(S1-x, Sex)3 exhibit high absorption coefficients, a tunable bandgap, and long-term stability. In addition, the advantages of their optoelectronic characteristics make them an emerging technology in PV applications.
