Thermal Stability and Photovoltaic Enhancement of Double Perovskite (Cs₂InSbCl₆) Based Solar Cell (p-i-n) through Thickness and Bandgap Optimization

This study utilizes SCAPS-1D simulations to demonstrate that optimizing the thickness and bandgap of a Cs₂InSbCl₆-based p-i-n solar cell with an Fe/CuO/CdS/TiO₂ heterostructure yields a high power conversion efficiency of nearly 28% with reduced recombination losses and acceptable thermal stability, establishing it as a promising candidate for next-generation photovoltaics.

Novel FeSi2 Driven Charge Transport Mechanisms in SnS Based Thin-Film Solar Cells.

This study utilizes SCAPS-1D numerical simulations to demonstrate that FeSi₂-driven SnS-based thin-film solar cells can achieve a maximum efficiency of 25.06% through optimized layer thicknesses and band alignment, while revealing that their performance is significantly limited by thermally activated interface recombination and shallow trap states.

A Butterfly Effect in Encoding-Decoding Quantum Circuits

This paper investigates information scrambling in noisy encoding-decoding quantum circuits, deriving an analytic expression for the algebraic out-of-time-order correlator that reveals a "butterfly effect" where infinitesimal noise induces macroscopic scrambling in the thermodynamic limit.

Probing topological phase transitions via nonlinear Hall response in strained moiré dice lattice

This paper demonstrates that the nonlinear anomalous Hall effect, driven by the Berry curvature dipole and significantly enhanced by broken chiral symmetry, serves as a robust probe for detecting topological phase transitions and sign reversals in strained, valley-polarized twisted bilayer dice lattices far from charge neutrality.
