Nanowires may boost solar cell efficiency, UC San Diego engineers say
Date:5/14/2008

e issue of polymer degradation. The polymers degrade quickly when exposed to air. Researchers around the world are working to improve the properties of organic polymers, said Paul Yu.

As it was a proof-of-concept project, the UCSD engineers did not measure how efficiently the device converted sunlight to electricity. This explains, in part, why the authors refer to the device in their NanoLetters paper as a photodiode rather than a photovoltaic.

Having a more efficient method for getting electrons to their electrode means that researchers can make thin-film polymer solar cells that are a little bit thicker, and this could increase the amount of sunlight that the devices absorb.
