New perovskite material shows promise alternative silicon
Silicon dominates solar energy products -- it is stable, cheap, and efficient at turning sunlight into electricity. Any new material taking on silicon must compete, and win, on those grounds. As a result of an international research collaboration have found a stable material that efficiently creates electricity - which could challenge silicon hegemony.

"Self-Healing" Polymer Brings Perovskite Solar Closer to Market
A protective layer of epoxy resin helps prevent the leakage of pollutants from perovskite solar cells, report scientists, adding a "self-healing" polymer to the top of a perovskite solar cell can radically reduce how much lead it discharges into the environment. This gives a strong boost to prospects for commercializing the technology.
