Special Issue Information

Dear Colleagues,

Organic-inorganic hybrid perovskite materials (OHP, AMX3, where A is organic or inorganic cation, M is metal cation, and X is a halogen anion) show considerable potential for solar cell and light-emitting diode applications. In solar cell applications, the power conversion efficiency is already over 25%, which is highly competitive in comparison with CdTe (22.1%), CIGS (22.6%), and Si (25.4%). To overcome the weakness of OHP materials, such as material instability, many researchers are focusing on studying instability origins, stable compounds, defect structures, and multi-functional hole transport layer (good hole mobility and water protection). This work is proceeding to engineering optimization now. However, its fundamental properties in thin films such as defects, phonon dispersion, and electronic structure are not fully understood, which is why many researchers are still attempting to improve its weakness in actual devices.

 This Special Issue of Nanomaterials, “Hybrid Perovskite Thin Film”, will be focused on (1) thin film fabrication; (2) basic characterizations with atomic, chemical, and electronic structures; (3) defects and their effects; and (4) suggesting possible new application using OHP materials.

To control the density of a CH3NH2 molecular defect, which strongly contributed to a significant THz-wave absorption property in the CH3NH3PbI3 hybrid perovskite thin film formed by the sequential vacuum evaporation method, we performed post-annealing processes with various temperatures and times. In the thin film after post-annealing at 110 °C for 45 min, the density of the CH3NH2 molecular defect was minimized, and CH3NH3I and PbI2 disappeared in the thin film after the post-annealing process at 150 °C for 30 min. However, the density of the CH3NH2 molecular defect increased. Moreover, the THz-wave absorption property for each thin film was obtained using a THz time-domain spectroscopy to understand the correlation between the density of a molecular defect and the THz-wave oscillation strength at 1.6 THz, which originated in the molecular defect-incorporated hybrid perovskite structure. There is a strong linear correlation between the oscillator strength of a significant THz-wave absorption at 1.6 THz and the CH3NH2 molecular defect density. Full article

Enhancement of Photoluminescence Quantum Yield and Stability in CsPbBr3 Perovskite Quantum Dots by Trivalent Doping

We determine the influence of substitutional defects on perovskite quantum dots through experimental and theoretical investigations. Substitutional defects were introduced by trivalent dopants (In, Sb, and Bi) in CsPbBr3 by ligand-assisted reprecipitation. We show that the photoluminescence (PL) emission peak shifts toward shorter wavelengths when doping concentrations are increased. Trivalent metal-doped CsPbBr3 enhanced the PL quantum yield (~10%) and air stability (over 10 days). Our findings provide new insights into the influence of substitutional defects on substituted CsPbBr3 that underpin their physical properties. Full article
