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