In the present study, the structural, mechanical, electronic and optical properties of all-inorganic vacancy-ordered double perovskites A2Sn1−xTixY6 (A = K, Rb, Cs; Y = Cl, Br, I) are explored by density functional theory. The structural and thermodynamic stabilities are confirmed by the tolerance factor and negative formation energy. Moreover, by doping Ti ions into vacancy-ordered double perovskite A2SnY6, the effect of Ti doping on the electronic and optical properties was investigated in detail. Then, according to the requirement of practical applications in photovoltaics, the optimal concentration of Ti ions and the most suitable halide element are determined to screen the right compositions. In addition, the mechanical, electronic and optical properties of the selected compositions are discussed, exhibiting the maximum optical absorption both in the visible and ultraviolet energy ranges; thus, the selected compositions can be considered as promising materials for application in solar photovoltaics. The results suggest a great potential of A2Sn1−xTixY6 (A = K, Rb, Cs; Y = Cl, Br, I) for further theoretical research as well as experimental research on the photovoltaic performance of stable and toxic-free perovskite solar cells.

Dimethyl sulfoxide (DMSO) is a versatile solvent used in many fields such as medicine and organic synthesis, whereas it is poisonous and harmful to human health. Physical and chemical properties, including bond length, dipole moment, total energy, frontier orbital energy, infrared absorption spectrum as well as the Raman spectrum of the DMSO molecule under an external electric field ranging from 0 to 0.03 atomic units were calculated by using the density functional theory (DFT) with the B3LYP/6-311G++(2d, p) basis set. According to the calculation, it has been found that as the external electric field increases, the two strongest infrared absorption peaks redshift and change in intensity. At the same time, a distinct new characteristic peak emerges in the Raman spectrum when the electric field is applied. Moreover, the Raman characteristic lines of DMSO were detected based on a self-designed Raman spectrometer. The potential energy curves under the increasing electric field were obtained by scanning the single-point energy along the S=O bond with the method B3LYP/6-311G (d, p). By fitting a linear curve between the potential barrier and the electric field, the intensity of the field corresponding to the zero potential barrier was computed. The results provide important theoretical references for further research about the DMSO’s physical and chemical properties and indicate that the structure and properties of molecules change significantly under an external electric field.

Due to the instability and toxicity issues of lead/tin-based halide perovskites, lead-free metal halide perovskites have emerged as an attractive lead replacement for several semiconductor applications. Here, we present a bismuth (Bi)-based perovskite structure as a low-toxic and potentially substitutable alternative to lead-based perovskite solar cells. The synthesis and optical performance of MAPbI3, MA3Bi2I9Clx, and (MAPbI3:BiCl3) with ratios (of 10, 30, 50, 70)% as lead-free and low lead perovskite are prepared. The grinding technique is used as a green chemistry method compared to a typical reaction for scaling up production. The phase identification, crystallinity, thermal stability, optoelectronic properties, and nanoscale composition are comprised. The results showed that the prepared samples are enhanced in the visible absorption region and aligned well with previous literature. Besides, the bandgap energy for the mixed-structured perovskite, at a molar ratio of 10%, was reduced to 1.52 eV compared to 1.55 and 1.80 eV for MAPbI3, MA3Bi2I9Clx, respectively. At room temperature, the samples emitted intense photoluminescence in the 680–700 nm region. Our findings demonstrate the processability of bismuth perovskites, aiding in the development of high-performance low toxic perovskites by assisting in the refinement of materials and processing methods.
