Methylammonium lead trihalide perovskite solar cells (CH3NH3PbY3, where Y = I(3 - x) Br-x (= 1 -3), I(3 - x) Cl-x = 1 (-3), Br(3 - x) Clx = 1 -3, and IBrCl) are photonic semiconducting materials. Researches on various fundamental and technological aspects of these materials are extensively on-going to make them stable environmentally and for commercialization. Research studies addressing these materials as organometallic are massively and repeatedly appearing in reputable and high-profile peer-reviewed journal publications (viz. Energy and Environmental Science, Nature Chemistry, Nature Communication, Advanced Materials, Science, ACS Nano, ACS Energy Letters, and in many other chemistry and materials based international journals). Herein, I candidly addresses the question: whether should scientists in the perovskite and nanomaterials science communities refer CH3NH3PbY3, as well as other perovskite derivatives falling into the same category, as organometallic?
