Antimony Selenide (Sb2 Se3) Measurement Sb2 Se3 is an interesting material for potential use in thin film solar cells as an absorber. A sample of Antimoniy Selenide layer deposited on Au foil was measured using MProbe VisNIR system(450-1700nm wavelength range).
Fig. 1 Reflectance spectra of Sb2 Se3 taken at the different point of the sample. The spectra show that the sample thickness is non-uniform. Sb2 Se3 is absorbing in the visible range up to ~ 750 nm.

Fig. 2. Model to measurement fit (central point). Thickness and optical dispersion of the Sb2 Se3 was determined from the measurement, Thickness= 818nm
Fig. 3 Optical dispersion of the Sb2 Se3 is determined from the measurement. Dispersion is represented using CauchyK model.
