Nanopillar Solar May Cost 10x Less Than Silicon 199
Al writes "A team of researchers from the University of California, Berkeley, have developed a new kind of flexible solar cell that could be far cheaper to make than conventional silicon photovoltaics. The cells consist of an array of 500-nanometer-high cadmium sulfide pillars printed on top of an aluminum foil — the material surrounding the pillars absorbs light and releases electrons, while the pillars themselves transport the electrons to an electrical circuit. The closely packed pillars trap light between them, helping the surrounding material absorb more. This means the electrons also have a very short distance to travel through the pillars, so there are fewer chances of their getting trapped at defects and its possible to use low-quality, less expensive materials. '"You won't know the cost until you do this using a roll-to-roll process," says lead researchers Ali Javey. "But if you can do it, the cost could be 10 times less than what's used to make [crystalline] silicon panels."'"

Just think one day we can grow massive "pillars" in the earth, and these "pillars" can sequester carbon and be powered by the sun as they grow. Then as they reach a certain height and are no longer as efficient as they once were, we can take them down and use them as fuel. We can then plant new pillars to grow and use the by products from old burnt "pillars" to help the new ones grow. Perhaps then if we properly manage these "pillar farms" and modify the "pillars" just right we can have them absorb more carbon from the air than they release when burned for fuel.
Perhaps, but is that technology "green"?

But then we'd have these "pillars" all over the place and would not be able to see the forest for them.
