Additions of copper iodide (CuI), rubidium iodide, or cesium to perovskite precursor solutions accelerated the formation photoactive α-phase formamidinium lead triiodide (FAPbI3) crystals. In particular, addition CuI suppresses low-dimensional phases, thereby reducing carrier transport. The first-principles calculations revealed that substituting Cu at site could maintain effective mass ratios α-phase. FAPbI3 is expected enhance its photovoltaic properties. Moreover, introducing into suggested as a new approach accelerate α-FAPbI3 phase.

Although perovskite-structured materials have primarily been widely employed in solar cell applications, limited studies conducted the field of electrorheology (ER). In this study, various halide perovskite materials, including FAPbBr3, FAPbI3, MAPbBr3, MAPbI3, CsPbBr3, and CsPbI3 were synthesized for first time to evaluate their applicability ER time. Initially, morphological chemical properties these characterized confirm successful formation structures. addition, as-synthesized dispersed silicone oil (3.0 wt %) suitability as dispersants fluids. Among these, CsPbI3-based fluid exhibited optimal dielectric greatest dispersion stability systems examined. demonstrated highest performance, achieving a shear stress 99.4 Pa, owing synergistic effects its intrinsic rod-like structure properties, which promoted polarization.

Perovskite solar cells have attained high photoconversion efficiencies by changing chemical compositions of the perovskites and layered structures devices. However, perovskite compounds easily decompose in air atmosphere even at room temperature, photovoltaic properties are degraded formed defects. The motivation this work is to solve these instability problems, objective present improve film quality introducing lanthanide elements decaphenylcyclopentasilane (DPPS), which were expected contribute decrease defects passivation effects. Here, effects neodymium trifluoride (NdF3) or ytterbium (YbF3) addition CH3NH3PbI3 inserted with DPPS investigated. Introduction NdF3 YbF3 increased lattice constants promoted crystal growth perovskites, surface treatment suppressed PbI2 formation as passivation. Combined additions contributed improvement both conversion devices stabilities inhibiting decomposition.

Although CH3NH3PbI3-based perovskite compounds have excellent photovoltaic properties, the lead (Pb) is harmful to environment, and Pb-free are needed for next generation solar cells. Theoretical calculations could be one of good methods design compounds, first-principles calculation was used predict properties present proposed materials. The instability organic molecules such as CH3NH3 also a problem, alkali elements cesium rubidium improve stability. From these point view effects tin (Sn) or germanium (Ge) on lead-free Cs- Rb- -based perovskites including double structures were investigated by in work. For standard single structures, with chlorine suitable band gap energies, higher electron mobilities, performance compared other iodine bromine-based perovskites. bromine found halogen, Ge provided density than Sn. wider energies improved stability perovskites, affected hybridization Sn/Ge halogen ions.
