Fabrication and investigation of a new highly humidity stable nanocrystalline perovskite, tetramethylammonium lead triiodide to be used in solar cells

Stabilizing tetramethylammonium lead iodide perovskite and exploring its electronic and optical absorption for solar cell absorber application

“…In comparison, both tetragonal and hexagonal structures were modeled with initial lattice parameters a = 6.43 Å, c = 4.60 Å, and a = 9.77 Å and c = 7.91 Å, respectively, from the experimental study of ref. 23 The cutoff for the wave function of cubic, tetragonal and hexagonal structures was converged to 60 Ry, the Monkorst-Pack k point grid, and the lattice parameter convergence was also achieved for the three structures within the 1 mRy per atom convergence criteria. The Murnaghan equation of state 32 curve fitting was carried out to determine the optimized lattice parameters.…”

“…Different stoichiometric ratios of cationic dyes and metal halides are also used as screening parameters in experimental studies. 4 Only a few studies are available on (CH 3 ) 4 NPbI 3 ; these available studies focused on experimental thermodynamic functions, 12 thermally induced reversible phase transitions, 9 fabrication of stable nanocrystalline (CH 3 ) 4 NPbI 3 23 and the use of the quaternary ammonium cation in stabilizing halide perovskites. 13 To search for a highly efficient and stable perovskite-based solar cell absorber, we calculated the electronic structure of (CH 3 ) 4 NPbI 3 using density functional theory and self-consistent GW quasiparticle methods within the many-body perturbation theory.…”

Scintillation properties of ((CH3)4N)3BiCl6 as a novel lead-free perovskite halide crystal

“…However, MAPbX 3 crystals, especially MAPbI 3 , degrade into PbI 2 in the presence of air, which reveals a rather poor stability because of the weak interaction of organic-inorganic in MAPbI 3 , while both MAPbBr 3 and MAPbI 3 crystals show high light yield of 200,000 photons/MeV at 10 K, although they quench at RT [40]. In order to overcome the stability problem, Jafarzadeh et al fabricated tetramethylammnonium lead iodide (TMAPbI 3 ), which showed acceptable stability [41]. In 2019, Banerjee and Gayen reported TMA-based lead free perovskite (TMASnI 3 ) suitable for cheap and moisture stable environmental-friendly perovskite solar cells [42].…”

Effect of particle size on the optical properties of lead zirconate titanate nanopowders

“…In recent years, the dielectric, piezoelectric, and optical properties of nanosized ferroelectric materials with perovskite structure have been considered by many researchers . The nanosized materials have more surface area to volume than larger particles and display novel optical, electrical, mechanical, and chemical properties.…”

“…In recent years, the dielectric, piezoelectric, and optical properties of nanosized ferroelectric materials with perovskite structure have been considered by many researchers. 1,2 The nanosized materials have more surface area to volume than larger particles and display novel optical, electrical, mechanical, and chemical properties. Among a large number of ferroelectrics material, lead zirconate titanate (PZT) ceramics with general formula Pb(Zr x Ti 1Àx )O 3 have attracted the attention of many researchers due to their interesting piezoelectric, pyroelectric, 3,4 dielectric energy storage capabilities, 5,6 mechanical, 7 electrical, 8 electromechanical, 9 and electrocaloric effect.…”
