LARGE AREA THIN FILM CADMIUM SULFIDE SOLAR CELL ARRAY INVESTIGATION
Abstract
A 5.1% thin-film cell was produced on a 1 in. x 1 in. substrate. This result compares favorably with the maximum efficiency of 5.4% reported for a single crystal CdS cell. A procedure for up grading low efficiency cells to the average efficiency level was also developed. A non destructive x-ray technique was used success fully to photograph dislocations in single crystal CdS. This procedure promises to yield a fund of information. Efforts to produce an ultrapure CdS by distillation of the elements and subsequent reaction is underway. Work was carried on in the analysis of the I-V data and spectral response in an effort to catalog this data in the form of a. The present data can be in an effort to catalog this data in the form of a model. The present data can be made to fit a p-n junction with photoconductive series and shunt resistances. Some reject 'shorted' cells were studied at low temperatures where the I-V curve begins to resemble a back ward diode. Injection luminescence with very low conversion efficiency was observed with the radiation lying in the band between 1 and 1.5 ev.
