New kind of “tandem” solar cell developed

(March 24, 2015)  Researchers combine two types of photovoltaic material to make a cell that harnesses more sunlight.

The development could lead to photovoltaic cells that are more efficient than those currently used in solar-power installations, the researchers say.
