Team sets solar cell record
Using a novel technology that adds multiple innovations to a very
high-performance crystalline silicon solar cell platform, a consortium led
by the University of Delaware has achieved a record-breaking combined solar
cell efficiency of 42.8 percent from sunlight at standard terrestrial
conditions.
