The impact of CBz-PAI interlayer in various HTL-based flexible perovskite solar cells: A drift-diffusion numerical study

Heliyon, Год журнала: 2024, Номер 10(10), С. e31138 - e31138

Опубликована: Май 1, 2024

In perovskite solar cells (PSCs), the charge carrier recombination obstacles mainly occur at ETL/perovskite and HTL/perovskite interfaces, which play a decisive role in cell performance. Therefore, this study aims to enhance flexible PSC (FPSC) efficiency by adding newly designed CBz-PAI-interlayer (simply CBz-PAI-IL) perovskite/HTL interface. addition, substantial work has been carried out on five different HTLs (Se/Te-Cu

First-Principles Investigation of Structural, Electronic, Optical, Elastic, and Thermoelectric Properties of Cubic Francifluorite Perovskites FrXF3 (X = Si, Ge, and Sn) for Optoelectronic and Thermoelectric Device Applications

Physica Scripta, Год журнала: 2024, Номер 99(12), С. 125979 - 125979

Опубликована: Ноя. 13, 2024

Abstract This study employs first-principles calculations based on Density Functional Theory (DFT), implemented in the Wien2k code, to investigate structural, electronic, optical, elastic, and thermoelectric properties of FrXF 3 (X = Si, Ge, Sn) compounds. Various exchange–correlation functionals, including GGA-PBE, GGA-PBEsol, GGA-WC, TB-mBJ, were utilized achieve a comprehensive analysis. The electronic structure reveal that all compounds exhibit semiconducting behavior with direct band gaps (R→R), ranging from 1.75 eV 2.68 using TB-mBJ. Optical analysis shows strong responses visible ultraviolet range, highlighting their potential for optoelectronic applications. Thermoelectric evaluations, thermal electrical conductivity, Seebeck coefficient, power factor, figure merit, indicate possess significant potential, positioning them as promising candidates

Impact of Sputtered AZO Seed Layer Thickness on Hydrothermally Grown ZnO Nanowires Properties for Flexible Perovskite Solar Cells

Advanced Engineering Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 11, 2025

Understanding the impact of aluminum zinc oxide (AZO) seed layer thickness on nanowires (ZnO NWs) growth is decisive in attaining high‐quality NWs with higher transparency and without cracking issues when using flexible substrates, especially for optoelectronic applications. Therefore, herein, ZnO have been grown various thicknesses AZO films deposited onto substrates (PET, PET/ITO (60 Ω sq −1 ) (200 )) through a simple, low‐temperature hydrothermal process. Based thickness, structural, optical, morphological, topographical properties systematically investigated. The results demonstrate that 1) thicker (≈250 nm) increase crystallinity than thinner (≈200 100 nm). 2) different ITO grades or 200 provide an optical bandgap value 3.24–3.27 eV offer good transmittance (>80%) visible range. 3) film strongly influences growth, NWs’ average diameter density. 4) Annealing samples at °C after NW pointless. Overall, findings efficient tuning exhibit promising potentiality perovskite solar cells, which also preliminarily tested.
