Vapor CdCl2-Optimization and Screening Experiments for an All Dry Chloride Treatment of CdS/CdTe Solar Cells

PDF Version Also Available for Download.

Description

A dry vapor treatment of CdCl2 is being developed as an alternative approach to the conventional solution CdCl2 treatment of CdS/CdTe devices. In this alternative process, the CdS/CdTe substrates are vapor treated in a close-spaced sublimation configuration. A 16-run Plackett-Burman screening experiment identified source temperature, substrate temperature, and treatment time as being the most significant parameters in the process. Subsequently, a 20-run Central Composite Design showed that a source temperature of 380-390 C, a temperature gradient (DT) of 5 C, and a time of 10 minutes provides the most process tolerant combination, yielding a total-area efficiency of 12.6%. A strong ... continued below

A strong interaction between DT and treatment time was also identified. The model indicated that for a small DT, device performance improved with decreasing time, whereas at larger values of DT, performance increased with increasing time.
