“…Now, MHPs have developed into a broad range of materials with the general formula ABX 3 , where A and B are monovalent and divalent cations, respectively and X stands for anions. Besides, MHPs have been widely used as active materials in various optical and electronic applications, such as photovoltaic devices (PV) ( Kojima et al, 2009 ; Kim et al, 2012 ; Lee et al, 2012 ; Jeong et al, 2021 ), light-emitting diode ( Cho et al, 2015 ; Cao et al, 2018 ; Lin et al, 2018 ), photodetector ( Li et al, 2020a ; Li et al, 2020b ), laser ( Sutherland and Sargent, 2016 ; Wei et al, 2019 ), sensor ( Zaza et al, 2019 ; George et al, 2020 ), biomedicine ( Fang et al, 2021 ; Zhang et al, 2021 ; Fang et al, 2022 ) etc.…”
