Nature examines thin-film and other solar cells

Darkfrog submitted, created time 5 months 6 days (www.nature.com)

There are a few different varieties of solar cell on the market and in development, but they've all got their ups and down. Traditional solar cells are now an established technology, but they are very expensive to make and their efficiencies don't top 22%. Other, newer types of solar cells (with one exception) are even less efficient, but they are much less troublesome to mass-produce. Some types of solar cells can even be woven into cloth.

As always, I'm a fan of Natures whole-picture approach. The practical, hopeful and economic aspects of this project all get their treatment.
