    Perovskite (pronunciation: / p ə ˈ r ɒ v s k aɪ t /) is a calcium titanium oxide mineral composed of calcium titanate (Ca Ti O 3).Its name is also applied to the class of compounds which have the same type of crystal structure as CaTiO 3 (XII A 2+ VI B 4+ X 2− 3), known as the perovskite structure. Many different cations can be embedded in this structure, allowing the development

  • An approach to optimize pre-annealing aging and anneal

    Dec 19, 2018· In this study, we reported a low-temperature, one-step solution process to fabricate perovskite solar cells using dehydrated lead acetate as the lead source. These perovskite films were aged at 200 s before thermal annealing at 90 °C for 5 min. Uniform perovskite films with lesser pinholes were obtained by this technique. The inverted planar (n-i-p) perovskite solar cell device resulted in a
