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.

It would be great if you could get some more info – my question is how the need for concentrators is done away with. They talk about a 20x concentration ratio . . . how? It’s unclear to me.
