Solar cities of the future will be powered by windows that can generate electricity
“Smart windows” with the ability to generate electricity are the way of the future, and scientists are another step closer to making it a widespread reality. Dye-sensitized solar cells—which are thin, flexible materials that can create see-through electronic circuits—could equip buildings with windows that make electricity. One day, they could do it better than current solar panel technology. But a lack of understanding how the dye interacts with a semiconductor surface on a molecular level is holding the technology back from making it more efficient.
