Abstract :
We show that the Photo-Acoustic Spectroscopy
(PAS) is an useful alternative method for the determination
of the optical-absorption coefficient of CdTe thin films, in
the spectral region near to the fundamental absorption
edge, ranging from 1.0 eV to 2.4 eV, using an open cell in
the transmission configuration. We applied this method to
the optical characterization of CdTe layers for several
values of their thickness. These CdTe samples were
deposited by closed-space vapor transport (CSVT) technique
under different growth conditions
