Researchers have grown dense arrays of single-crystal semiconductors arranged as nanoscale pillars on low-cost, aluminum foil substrates. When the nanopillars are combined with a transparent, positively charged semiconductor that serves as a window, the resulting 3-D photovoltaic promises efficient, cheap, flexible solar cells.
