Performance Optimization of Lead-Free Cs2AgBiI6 Solar Cells with the LBSO Electron Transport Layer: A SCAPS-1D Simulation Study

Abstract Lead toxicity in conventional halide perovskites has long been a concern for practical photovoltaic deployment, and Cs2AgBiI6 double perovskites gained significant attention as promising lead-free alternatives due to their high carrier mobility, suitable optoelectronic c...

Dual-functional Amino–Sulfonic acid interfacial passivation for efficient perovskite solar cells

Interfacial defect passivation is essential for suppressing non-radiative recombination (NRR) and charge accumulation, which limit the performance of inverted perovskite solar cells (PSCs). Herein, we introduce DSDA (4,4′-diamino-2,2′-stilbenedisulfonic acid) as a multifunctional...

Model-Driven PerformanceOptimization of Lead-FreeRbGeI3 Perovskite Solar Cells Using SCAPS-1D

Abstract Driven by the urgent global requirement for sustainable and nontoxic photovoltaic materials, employing a combined DFT and SCAPS-1D computational framework, this study evaluates the electronic structure and photovoltaic performance boundaries, defined here as the efficien...
