You've probably noticed that solar panels sitting on people's roofs appear to be broken up into grids. These grid lines are actually metal contacts and, although they're necessary for conducting the electrical current generated by the underlying semiconductor, they reduce the amount of sunlight reaching the semiconductor layer. Now researchers at Stanford University have developed a way to make these reflective metal contacts almost invisible to incoming light, thereby increasing solar panel efficiency.
