Discovery of a 'Dark State' Could Mean a Brighter Future for Solar Energy

Zhu said that exploiting that mechanism could increase solar cell efficiency to 44 percent without the need for focusing a solar beam, which would encourage more widespread use of solar technology.

44% can be huge. The potential 60+% even huger. And having a cheap material to make solar panels can make this the thing that will finally bring a solar-panel-roof to every house. Could it be?

Rember though we’re talking about a laboratory experiment, most of which don’t ever become marketable hardware. We can hope though.
