Researchers at the California Institute of Technology in Pasadena have developed new solar cells. These use a new kind of silicon nanorod assembled into something resembling a carpet that can be embedded into a transparent polymer and made flexible. The new solar cells use only 1% of the material needed to produce traditional silicon solar cells.

The hope is that these new solar cells, with their silicon base, will be easily adopted by existing solar cell manufacturing plants and will make solar cells cheaper and more readily available to home builders.
