UNH researchers and Conductive Compounds Inc. in Hudson recently received $450,000 from the National Science Foundation to help produce more conductive and cost-effective solar panels. The three-year grant, under the GOALI (Grant Opportunities for Academic Liaison with Industry) program, will support the engineering of nanoparticles of silver suitable for screen-printing onto photovoltaic (PV) solar panels.
To generate electricity from the sun, solar panels must have metal on the top and bottom to create a positive and negative connection, like a battery. Coating the shaded bottom side is fairly easy, but on the top, panels are screen-printed with lines of silver fine enough that they maximize light exposure.
“But the ink that creates these lines is not nearly as conductive as pure silver,” says principal investigator Dale Barkey, professor of chemical engineering. “We’d like to produce inks that are much more conductive than the ones on the market.”
