Effect of CdCl2 treatment on structural and electronic property of CdTe thin films deposited by magnetron sputtering

Optimization of physical properties of vacuum evaporated CdTe thin films with the application of thermal treatment for solar cells

“…Generally, angular position shifts toward higher and lower sides due to decrease and increase in the corresponding lattice constants respectively. The results are in good agreement with the earlier reported works of Islam et al [16,38].…”

The study of CdSe thin film prepared by pulsed laser deposition for CdSe/CdTe solar cell

“…The thickness of the CdTe thin film was kept as around 4-6 lm to make sure that the photons were sufficiently absorbed. The fabricated CdSe/CdTe layers were treated by using the usual CdCl 2 saturated solution, and were annealed at 385°C for 35 min to form the rich Te layer, which can increase the p-type property of CdTe thin film [14,15]. A thickness of about 70 nm of ZnTe:Cu back contact layer grown by PLD under room temperature was covered on the etched CdTe layer.…”

Effect of deposition power in fabrication of highly efficient CdS:O/CdTe thin film solar cell by the magnetron sputtering technique

“…After the deposition, the samples were left in the chamber until the temperature cooled down to room temperature. The CdCl 2 thermal treatment was employed using the parameters optimized previously [32]: the samples were dipped into 0.3 M CdCl 2 solution for 10 s, the mixed samples were dried in air at about 10 min and treated in an evacuated furnace of N 2 /O 2 ambient for 15 min with a constant pressure (500 mT) and temperature (390°C). At the end of the annealing process, the samples were left in the annealing chamber until the chamber is cooled down to room temperature.…”

“…In fact, the chloride activation induces crystal regrowth in CdTe films. The wet process CdCl 2 activation was first optimized [32] and then employed for crystal regrowth in CdTe films. The SEM images (Fig.…”
