On the road to nontoxic and stable perovskite solar cells

Halide perovskite materials show high efficiency for solar energy technologies, but this comes at a cost: The best perovskite materials incorporate toxic lead, which poses a hazard to the environment. Replacing lead with less toxic elements is difficult because lead-free perovskites have lower stability and poor efficiency. Now, an international collaboration has engineered a new hybrid perovskite material with promising efficiency and stability.
