Paper-thin solar panels made - on paper

U.S. researchers say they've developed a flexible and extremely thin solar technology that can be printed on paper to create a working solar cell. Scientists at the Massachusetts Institute of Technology say the technology could allow the solar industry to transition away from large, expensive installations and toward the possibility of easily generated renewable electricity almost anywhere, the Los Angeles Times reported Thursday. The MIT researchers say vaporous inks made from common elements rather than pricey, toxic components like tellurium normally utilized in solar cells can create cells on plain, untreated paper, including tissue, tracing paper and even newsprint. The paper can be shaped and folded and still generate electricity when unfolded, and the cells have proven to be long lasting, the researchers said. Current commercial solar options require glass and heavy support structures, whereas paper cells could be taped to a wall, attached to laptops or made into window shades or clothing and even laminated to withstand harsh weather, the researchers said.
