In perovskite solar cells (PSCs), the charge carrier recombination obstacles mainly occur at the ETL/perovskite and HTL/perovskite interfaces, which play a decisive role in the solar cell performance. Therefore, this study aims to enhance the flexible PSC (FPSC) efficiency by adding the newly designed CBz-PAI-interlayer (simply CBz-PAI-IL) at the perovskite/HTL interface. In addition, substantial work has been carried out on five different HTLs (Se/Te-CuO, CuGaO, VO and CuSCN, including conventional Spiro-OMeTAD as a reference HTL with and without CBz-PAI-IL), using drift-diffusion simulation to find suitable FPSC design to attain the maximum PCE.

In this work, we have conducted an ab initio computational research of the pressure impact on the structural, elastic, thermodynamic, electronic, and optical properties of Be-based fluoroperovskite XBeF3 (X= K, Rb) compounds by using GGA+ PBEsol functional based on DFT in the CASTEP Package. These compounds' ground state characteristics were examined, including the lattice parameters, coefficient compressibility (B), and its pressure derivative(B'). Structural characterization shows that these compounds keep a cubic crystal structure with the impact of stress till 18 GPa.

Introduction: Biological rhythms, such as Light/Dark (LD) cycles, are an integral component of virtually all aspects of life. These rhythms are controlled in large part by circadian clocks, allowing the organism to adapt its internal rhythmic metabolism to changes in the external environment created by daily fluctuations in the LD cycle. Therefore, changes in the daily duration of the lighting could lead to adverse health consequences.
