Tiny solar cells fix themselves
Found on BBC News on Saturday, 04 September 2010
Researchers have demonstrated tiny solar cells just billionths of a metre across that can repair themselves, extending their useful lifetime.
The cells simply assemble themselves from a mixture of the proteins, minute tubes of carbon and other materials.
That's pretty amazing, but it would be even better to see a widespread use of traditional solar cells. The technology does not only need to advance, but it needs to get way cheaper.
