Solar Cells From Inexpensive, Low-Grade Silicon
Researchers have made flexible solar cells by carving light-trapping nanostructures into thin strips of low-grade silicon (Nano Lett., DOI: 10.1021/nl3020445). Because the cells use tiny quantities of inexpensive, low-quality silicon, they should cost much less than rigid crystalline silicon cells on the market, says Akram Boukai, a materials science and engineering professor at the . . .
