HOIPs are in a class of material that has a perovskite crystal structure with an ABX3chemical composition, where A, B, and X represent an organic monovalent cation, an inorganic cation and a halogen, respectively. Methylammonium lead iodide (MAPbI3) perovskite, which, as the name suggested, ...
The active energy barrier and reaction heat in the first step are 0.1 kcal/mol and −2.7 kcal/mol. The reaction is an exothermic reaction due to the reaction heat being a negative value because energy is released during the N-N bonding process. The energy barrier is so small as to be...
