The objective of this program, Part 2 of the Silicon Materials Task, is to develop and define purity requirements for solar cell grade silicon material by evaluating the effects of metal impurities and impurity concentration on the performance of terrestrial silicon solar cells. During this quarter the growth of all first generation doubly-doped Czochralski ingots was completed (baseline boron + Cr, Mn, Cu, Ni, Fe, Ti, V, Mg, Zn, Al, and Zr), as were 90 percent of the second generation ingots, several third generation ingots, and three multiply-doped (B + Cu/Mn, Cu/Cr, Mn/Cr) ingots.
