(March 24, 2015) Researchers
combine two types of photovoltaic material to make a cell that harnesses more
sunlight.
Researchers at MIT and Stanford University have developed a
new kind of solar cell that combines two different layers of sunlight-absorbing
material in order to harvest a broader range of the sun’s energy. The
development could lead to photovoltaic cells that are more efficient than those
currently used in solar-power installations, the researchers say.
