Problem Addressed

Perovskite devices have increased their efficiency from 6.5% to 20.1%. However, there are two central issues with commercialization of perovskite solar cells, the toxicity, and the long-term stability of the lead-based materials. This design simultaneously mitigates the toxicity and instability of the perovskite materials by introducing a second less-toxic metal species into the perovskite film.
