Abstract Organic–inorganic hybrid perovskite solar cells (HPSCs) are gaining attention as a promising technology for next‐generation photovoltaic devices owing to their impressive power conversion efficiency (PCE) and cost‐effective fabrication methods. Although, solution‐processed passivation using 2D perovskites can improve the interface recombination, this approach hampers its effective charge transportation. In study, study investigates properties performance of bilayer 3D/3D methylammonium lead iodide (MAPbI 3 )/formamidinium (FAPbI )‐based heterojunction (BPHJ) address these concerns. The structure consists two distinct absorbers having independent that sandwiched between transporting layer (CTLs) make functional device. First, process is optimized achieve high‐quality MAPbI films with controlled morphology crystallinity followed by formation BPHJ FAPbI deposition thermal evaporation technique. BPHJ‐160 nm‐based PSCs parameters exhibit an enhanced PCE 23.08% compared single‐layer reference (20.15%) improved be attributed extraction at reduced recombination losses due favorable energy levels. Furthermore, long‐term stability BPHJ‐based device assessed under continuous illumination along ambient across different environmental conditions.

Published: Feb. 4, 2025

Abstract In the pursuit of higher conversion efficiency, PV industry has turned its focus towards perovskite-silicon tandem solar cells, which currently represent peak innovation. To surpass efficiency limits traditional single-junction researchers are exploring potential these cells by integrating merits perovskite and silicon. However, brings different challenges, such as deposition methods material misalignments. Thus, in this work, we using advanced simulation techniques, including Silvaco ATLAS’s Victory Process Device Simulator to imitate actual manufacturing processes. Primarily research work focuses on three scenarios: shunting, planarization conformal emulate experimental conditions. The obtained results show effectiveness process simulations accurately predicting improving performance cell. Two designed showed a 27.51% 29.08% respectively. This highlights importance tools for further development cell technology. Detailed device reported may pave way fabrication optimised perovskite/silicon

Published: Feb. 25, 2025

Abstract In the quest for high‐efficiency photovoltaics, tandem solar cells combining perovskite and CZTSSe (copper zinc tin sulfide selenide) hold significant promise. This study explores integration of diphenylammonium chloride (DPACl) as an additive within a wide‐bandgap (WBG) layer to enhance performance four‐terminal (4‐T) hybrid (HTSCs) device. The DPACl has been systematically optimized utilized WBG (PSCs). Here, optimum amount effectively enhances quality films, improves charge carrier dynamics thereby reducing non‐radiative recombination losses. An 2 mg mL −1 DPACl‐based PSC achieved power conversion efficiency (PCE) 19.66% with thehighest open circuit voltage (V OC ) 1.172 V. Further, WBG‐based PSCs integrate into 4‐T mechanically stacked narrow bandgap (NBG‐1.05 eV)‐based HTSCs, which demonstrates high PCE 23.96%. research contributes essential insights development efficient photovoltaic systems based on architectures.
