Silicon materials task of the Low Cost Silicon Solar Array Project (Part 2). Fifth quarterly report and summary, 1 October 1976--31 December 1976. [Definition of purity requirements]
The objective of this program is to develop and define purity requirements for Solar Grade Silicon by exploring the effects of metal impurities on the performance of terrestrial silicon solar cells. The first phase of this effort is now completed. Fifty-two Czochralski ingots and forty-four dendritic web specimens have been grown, chemically analyzed, sampled, and tested for OCD and PCD lifetime and solar cell performance. The results of this study, compiled with much of the experimental data, are intended both as a summary of the work and as a reference for metal impurity effects on silicon solar cells.
