Researchers at MIT have developed an organic dye that could turn ordinary windows into solar panels. Applied as a coating to one side of a glass sheet, the dyes absorb sunlight and emit it into the glass, where it is channeled to narrow solar cells along the edge, producing electricity. "This could be the cheapest solar technology," says MIT engineering professor Marc Baldo. "And I think one day, it could be competitive with coal."
