Flexible, inexpensive, large-area, lightweight solar cells are difficult to produce as they require an inert atmosphere and high temperatures, and they often degrade in a short time after exposure to air. Researchers at MIT, however, have used a new method to craft solar cells from ultra-thin layers of quantum dots in a process that promises to avoid these problems, and at room temperature. At the same time, they have also set a new record of nine percent for the most efficient quantum-dot solar cells produced to date...
