A new solar technology converts carbon dioxide into a hydrocarbon fuel using only sunlight for energy
A solar cell that converts atmospheric carbon dioxide into hydrocarbon fuel
RESEARCHERS HAVE achieved a breakthrough in solar technology—a solar cell that cheaply and efficiently converts atmospheric carbon dioxide (CO ) directly into 2 usable hydrocarbon fuel using only sunlight for energy. The technology to turn CO into fuel at a cost comparable to a gallon 2 of gasoline could render fossil fuels obsolete. Unlike conventional solar cells—which convert sunlight into electricity that must be stored in heavy batteries—the new device essentially does the work of plants, converting atmospheric CO into fuel, solving two crucial 2 problems at the same time. The new solar cell is not photovoltaic, it's photosynthetic. It is 1,000 times faster than noble-metal catalysts and about 20 times cheaper. Science, July 29
