Terra Firma or Aqua Corpus? Or, Where Best to Harness the Sun?

Floating solar farms have been installed on reservoirs in Great Britain and Japan, but have been slow to gain a foothold in the United States. Why?

Researchers at the Massachusetts Institute of Technology are seeking to increase the efficiency of solar cells by helping them take advantage of more of the sun’s rays.

MIT scientists are testing solar cells with a layer of carbon nanotubes that “make it possible to take advantage of wavelengths of light that ordinarily go to waste,” according to a statement yesterday from the Cambridge, Massachusetts-based university.

Standard polysilicon photovoltaic cells don’t “respond” to the entire spectrum of sunlight, limiting the amount of photons they’re able to convert into electricity. Scientists have said standard polysilicon has a theoretical maximum efficiency of 33.7 percent. The nanotube technology may be used to surpass that limit, according to Evelyn Wang, an MIT associate professor of mechanical engineering.
