Looks like there is a new coating being applied to solar panels. It allows panels to capture and absorb light from broader angles, therefore boosting panels light absorption efficiency by about 25% overall, and a possible increase of power of about 3-5%. More hope for a greener future! "Researchers have developed a new anti-reflective coating that boosts the efficiency of solar panels and allows sunlight to be absorbed from almost any angle. A typical untreated silicon solar cell absorbs just over two thirds of the sunlight it receives. But with the FCC's nanoengineered coating, that figure rises to 96.21 percent."
