An innovation from MIT may provide a way to do away with bulky solar panels.
Scientists at the MIT have created an inkjet-style printing technology that can successfully print solar cells on paper. The technology is still in its nascent stage however, and the cells are less than 2 percent efficient at converting sunlight to electricity. The scientists used carbon-based dyes but say that any material could be used if it can be deposited at room temperature. They believe this technology could pave the way for lightweight solar panels that can be easily installed using a staple gun.
