A Boston College team of researchers has developed an alternative means using a unique semi-metal that intrinsically generates direct current through the nonlinear mixing of the waves of light. Typically, light is converted to electricity by chemically altering a semiconductor to have a built-in electric field. The recently discovered Weyl semimetal delivers the largest intrinsic […]

A Big Improvement for Carbon Nanotube Solar Cells
September 4, 2014 | Leave a Comment
Northwestern University scientists have now developed a carbon nanotube solar cell (CNT) that is twice as efficient as its predecessors. Early research stalled when CNTs proved to be inefficient, converting far less sunlight into power than other methods. Yet the CNTs have long shown promise for photovoltaics because they’re lighter, more flexible, and cheaper than […]
