Dye-ing for efficient solar power

Solar energy is an abundant resource, but so far, solar panels have tended to be relatively expensive and less efficient than desired. Now researchers at MIT in Cambridge, Mass., may have solved both those problems by inventing a new inexpensive dye that works as a “solar concentrator” when painted on ordinary window panes. The dye gathers light energy over the entire surface of the window, then transports it out to the edge of the pane to a line of energy-collecting solar cells.
