For years, scientists have dealt with the problem of trying to increase the efficiency and drive down the cost of solar cells.
Now researchers have hit upon a new idea—trying to give the light collected by solar cells a bit of “amnesia.”
At the U.S. Department of Energy's (DOE) Argonne National Laboratory, nanoscientists Chris Giebink and Gary Wiederrecht, collaborating with Northwestern University Professor Michael Wasielewski, have investigated the use of fluorescent plastics called luminescent solar concentrators (LSCs) that can be used to lower the cost of electricity from solar cells.
