Crystal structure of cdte
WebCdTe-based PV is considered a thin-film technology because the active layers are just a few microns thick, or about a tenth the diameter of a human hair. ... includes the ability to deposit all the layers mentioned above as … Webkn is the crystal wave function, corresponding to energy εkn with momentum k. Due to the cubic structure of CdTe, the optical spectra are isotropic; consequently, only one component of the dielectric function is analyzed. The real part of the dielectric function ε()ω 1 is then calculated using the Kramers-Kronig transformation.
