Led by Tao Xu of NIU and Kai Zhu of NREL, the team has developed a technique to sequester the lead in perovskite solar cells, minimizing potential toxic leakage. Perovskite solar cell technology is considered a thin-film photovoltaic technology, since rigid or flexible perovskite solar cells are manufactured with absorber layers of 0.2- 0.4 m, resulting in even thinner layers than classical thin-film solar cells featuring layers of 0.5-1 m . The perovskite family of solar materials is named for its structural similarity to a mineral called perovskite, which was discovered in 1839 and named after Russian mineralogist L.A. Perovski. Since the first publication of all-solid perovskite solar cells (PSCs) in 2012, this technology has become probably the hottest topic in photovoltaics. Perovskite solar cells have shown remarkable progress in recent years with rapid increases in efficiency, from reports of about 3% in 2009 to over 25% today. A "perovskite" is any material that has the same crystal structure as the compound calcium titanium oxide. As silicon solar cells are about to reach their efficiency limit, the interest in tandem devices is strong, especially in perovskite-silicon tandem solar cells featuring higher efficiencies at potentially low costs. The simulations modeled shooting protons with various energies at a perovskite solar cell and determined how the proton beams would interact. This article previews the recent findings on most stable PSC to date.
