Researchers at the University of Illinois at Chicago have engineered a potentially game-changing solar cell that cheaply and efficiently converts atmospheric carbon dioxide directly into usable hydrocarbon fuel, using only sunlight for energy.
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 carbon dioxide into fuel, solving two crucial problems at once. A solar farm of such “artificial leaves” could remove significant amounts of carbon from the atmosphere and produce energy-dense fuel efficiently.
The technology should be adaptable not only to large-scale use, like solar farms, but also to small-scale applications. In the future, it may prove useful on Mars, whose atmosphere is mostly carbon dioxide, if the planet is also found to have water.

So many “break through” researches has been published already but the bolded part is the issue.
