Especially, perovskite recovered in the bleacher solution can be dispersed in nonionic solvents and then recast the perovskite film (Wang et al., 2021). The other way to achieve the cyclic utilization of PbI 2 is the in situ recycling of PbI 2 from pristine PSCs and regenerating new devices ( Jena et al., 2018, Xu et al., 2017 ).
Herein, we have presented systematic DFT calculations for physical properties of barium-based periodate double perovskite oxides Ba2AgIO6 and Ba2NaIO6 in cubic phase. Our calculations show that both compounds are stable in cubic phase with tolerance factor (τG) of 0.96/0.92 for Ag/Na based studied compounds. Optimization …
