Solar panels are proliferating across the globe to help reduce the world's dependency on fossil fuels. But conventional panels are not without environmental costs, too. Now scientists report a new advance toward more practical, "greener" solar cells made with inexpensive halide perovskite materials. They have developed low-bandgap perovskite solar cells with a reduced lead content and a power conversion efficiency of 15 percent.
