“…The annealing effect on structural parameters indicates that the degrees of preferred orientation along with the other microstructural features are more effective than the crystallite size. This type of correlation by other workers [22,23] for II-VI group compound thin films are in good agreement with our results for Bi 2 Te 3 film. The structural parameters calculated in the present work were consolidated in Table 1.…”

“…The factors have a strong influence on the absorption processes [8,21,22]. The intercrystallite boundaries, being highly disordered and a sink for impurities, can have properties very different from those of the crystallites giving a marked contribution to the absorption of the thin films [23]. This contribution has been modeled by considering the intercrystallite boundaries as an amorphous region [24].…”

“…Because of its low sublimation temperature CdTe polycrystalline films can be prepared by several techniques. [16][17][18][19][20][21][22] The close-space sublimation (CSS) technique is one of the techniques that have produced encouraging results. There have been many reports of CdTe doped with elements, including Sb, Ag, and Cd, Te enrichment etc.…”

Cadmium telluride (CdTe) thin films were prepared by the close-space sublimation (CSS) technique, using 99.99% pure CdTe powder as the evaporant. Films were then annealed at 400°C for 30 min and were later dipped in Cu(NO 3 ) 2 -H 2 O solution at 80 ± 2°C. After immersion these films were again annealed at 400°C for 1 h to ensure the Cu diffusion into the films. X-ray diffraction (XRD) results confirmed the formation of a new compound copper telluride and a change in the morphology was observed by scanning electron microscopy (SEM). The DC electrical resistivity reduced from 10 6 X-cm for as-deposited to 10 -3 X-cm for 15 h immersed film. As the wt.% of Cu increased, the mobility increased to some extent, while the carrier concentration showed a systematic increase. The film thickness and optical parameter such as refractive index, absorption coefficient, and the optical band gap were deduced by fitting the optical transmittance in the wavelength range 300 to 3000 nm. The transmission decreased with increasing immersion time of films in the solution. The Cu concentration was recorded as 0.9 wt.% for 3 min to 56.6 wt.% for 15 h immersed samples using an electron microprobe analyzer (EMPA). In the next step, ITO/CdS/CdTe heterojunctions with 10.9% solar cell efficiency were fabricated on glass slides.
