Nanopillar Solar Cells.

technologyreview.com — Researchers @ UC Berkeley made a new kind of solar cell by growing an array of upright nanoscale pillars on aluminum foil. The design could lead to solar cells that cost less than conventional silicon photovoltaics & the technique used to make the cells could be adapted to make rolls of flexible panels on thin aluminum foil, cutting manufacturing costs.
