Researchers at the University of Sheffield in the UK have created a spray-on solar cell that uses perovskite as the light-absorbing layer. Although the cell's efficiency is only a modest 11 percent, it can be manufactured very cheaply, paving the way for significant reductions in the cost of large-scale solar panel production.
