IMPROVED CDTE SOLAR CELL AND ARRAY ENVIRONMENTAL EFFECTS INVESTIGATION.
Abstract
Several one square inch cells have been made from light weight material and 2-12 micron CdTe films. These cells had a weight-to-area ratio of 0.022 pounds per square foot and a power-to-weight ratio of 140 watts per pound. A generally negative exponential dependence of cell leakage conductance on film thickness has been observed. Interesting results have been noted on films grown on moly substrates treated in a wide variety of different etchants. One particular new solution resulted in films with one-half to one-third the leakage conductance of films grown on substrates etched by the standard sulfate solution. Several prototype designs of a single-feed boiler are being evaluated. Further studies of single vs. double treatment, intermediate heat treatment, dip time and solution concentration have resulted in refinements of the Cu(+) barrier formation process. (Author)
