Researchers all over the world are racing to bump up the efficiency of plastic solar cells, and, thus far, physicist David Carroll of Wake Forest University appears to be in the lead.
Last year, Carroll and his team approached 5% efficiency with these cells, nearly 2% more than other cells at the time. Now, Carroll and his team report online, on April 19 in Applied Physics Letters, that they have achieved another 20% increase, bringing the total efficiency to more than 6%.
