Sublimation of Mg onto CdS/CdTe films fabricated by advanced deposition system

Plasma cleaning of TCO surfaces prior to CdS/CdTe deposition

“…2. [11] III. RESULTS AND DISCUSSION The initial neutral pressure conditions of 40 mTorr in the plasma cleaner were established by the process conditions 978-1-4673-0066-7/12/$26.00 ©2011 IEEE used in the ARDS.…”

Progress towards a CdS/CdTe solar cell implementing An Electron Reflector

“…Cd 1-x Mg x Te (CMT) alloy thin films are well suited for the ER application because they exhibit a substantial band gap increase with relatively low Mg content, x, and have a close lattice match to CdTe. Furthermore, as we showed in our previous work [4], the formation of Cd 1-x Mg x Te is thermodynamically favorable, making deposition of thin films accessible by standard deposition methods.…”

“…Deposition of CdS and CdTe films, CdCl 2 treatment, and Cu treatment were performed in the previously described Advanced Research and Development System (ARDS) at Colorado State University [4], [7]. Deposition of Cd 1-x Mg x Te thin films were performed in the previously described Deposition Research Chamber (DRC) [5] using a co-sublimation process suitable for large areas [6].…”

Growth and characterization of Cd<inf>1&#x2212;x</inf>Mg<inf>x</inf>Te thin films for possible application in high-efficiency solar cells

“…For a majority of the samples, Mg content increases with band gap and appears to replace the Cd content in the film. We have demonstrated earlier that formation of MgTe is thermodynamically favorable to formation of CdTe [6]. Therefore, Mg content of spots (a), (b), and (c) is limited by Mg flux present at that location.…”
