Abstract

The optical constants of vacuum-deposited CulnSe2 films were determined from the measured transmittance and reflectance at normal incidence of light in the wavelength range 500 to 2000 nm. The analysis of the experimental points of the absorption coefficient revealed the existence of two optical transition processes: an allowed direct transition withEg=1.03±0.01 eV and a forbidden direct transition withEf=1.254±0.001 eV. The optical constants of the films were independent of the substrate temperature.
