New techniques in making a sprayable liquid that works like a solar panel will make them both easier to install and cheaper to produce.  The new method is currently in development at a lab at the University of Sheffield in the United Kingdom. “The goal is to reduce the amount of energy and money required to make a solar cell,” David Lidzey, a physicist collaborating on the project, explains in a statement. “This means that we need solar cell materials that have low embodied energy but we also need manufacturing processes that are efficient, reliable and consume less energy.”
