cheap, flexible solar cells
- Interesting development
Cheap, plastic solar cells that can be painted onto just about any
surface could provide power for a range of portable and even wearable
electronic devices, scientists said Thursday.
A team at the University of California Berkeley said they had come up
with a first generation of plastic solar cells, which could someday
replace the bulky and expensive silicon-based cells used widely now.
"Our efficiency is not good enough yet by about a factor of 10, but
this technology has the potential to do a lot better," Paul
Alivisatos, a professor of chemistry who led the study, said in a
statement. "There is a pretty clear path for us to take to make this
perform much better."
