Similar to Sn-based perovskites, Ge-based perovskites also face the trouble of being easily decomposed by oxidation. Ordinary tap water may be used as the solvent for the acrylic acid monomer in the polymerization reaction, but as such water normally contains many ionic contaminants, and as these have been found to lower the viscosity of the polymer solution, distilled water is preferred, particularly where reproducibility of polymer properties is desired in batch to batch operations. 3(9), 20772085 (2018). Synthesis and characterization of cubic FASnI3 perovskite were first investigated in 1997 [94]. via DFT calculations and solid-state reactions indicated that all of the as-proposed AB(Ch, X)3 perovskites are thermodynamically unstable [34], and they tend to decompose into ternary and/or binary phases or form nonperovskite phases.
