Organic-inorganic hybrid perovskite solar cells, considered as a competitive alternative to conventional silicon solar cells, are prone to degrade when exposed to air. An international team of researchers (China, Greece, Australia) introduced PVP to the methylammonium lead iodide perovskite precursor. It can control crystal growth and endow the devices with self-healing ability in a moisture environment. When it was introduced in perovskite solar cells, it acted as a protective armor with an automatic blood backflow effect against water vapor. In addition, PVP can improve crystal growth with fewer defects and larger grains…read more. TECHNICAL ARTICLE
