Materials studies and solar cells made from various blends of UMG Si are compared with reference solar (PV) grade in terms of efficiencies, voltages, currents, diffusion lengths, minority carrier lifetimes and compositions. The UMG material used in this study performed unexpectedly well when used in cells manufactured both in a lab environment and on a commercial PV line. The limited number of cells of each composition does not support a full statistical analysis. However in comparing solar efficiencies, it is clear that a relatively minor delta exists between UMG blends and the particular PV grade material used in this study. That delta is between zero and 0.5 percentage points.
