Despite promising advances, challenges remain in optimizing the efficiency of lead-free PSCs for practical applications. This study investigates cesium germanium tri-iodide (CsGeI₃) as a lead-free perovskite absorber layer, with four zinc-based electron transport layers and five kesterite quaternary-based hole transport layers. Using the SCAPS-1D simulation software, 20 unique device structures were modeled, systematically varying the charge transport layers to identify optimal configurations. Zinc-based electron transport layers were chosen for their large band gaps and high optical transmittance, while kesterite-based hole transport layers were selected due to their high absorption coefficients, tunable band gaps, abundance, and non-toxicity. A systematic methodology is adopted to analyze the effect of the charge transport materials on the absorption, quantum efficiency, energy band alignment, electric field intensity, recombination rate, carrier density, thickness, doping concentration, temperature, reflection and interface defect densities of the PSC in detail. Notably, the CMTS/CsGeI₃/CdZnS structure achieved the highest power conversion efficiency of 25.78%, with a short-circuit current density of 24.49 mA/cm<sup>2</sup>, a fill factor of 86.39%, and an open-circuit voltage of 1.22 V.

The strategic selection of electron-donating/accepting groups, along with the π-bridge, in the design of light-harvesting dyes for DSSCs systematically enhances their photophysical properties to meet efficiency criteria and optimize DSSC performance. This study examines model dyes derived from triphenylamine (TPA) and indoline (IND), designated as TPA1, TPA2, TPA3, IND1, IND2, and IND3, each containing donor, bridge, and acceptor molecular units. The research aims to assess how different π-spacer configurations affect the optical, electronic, and photovoltaic properties critical for DSSCs. Using DFT and TDDFT methods, the study demonstrates that extending π-conjugation (in a D-π-π-A structure) causes a red shift in the absorption spectra by reducing the HOMO–LUMO gap. TPA2 outperformed the other TPA dyes with the highest short-circuit current density (J<sub>sc</sub>) of 1.75 mA cm⁻<sup>2</sup>, while IND2 led the IND series with a Jsc of 0.77 mA cm⁻<sup>2</sup>. Additionally, TPA2 showed superior regeneration kinetics, with the fastest regeneration rate (ΔG<sub>reg</sub> = 0.37 eV) and an open-circuit voltage of 0.88 eV. IND2, though achieving a competitive regeneration rate (ΔG<sub>reg</sub> = 0.67 eV), recorded the highest open-circuit voltage within the IND series at 1.47 eV. The strong correlation between computational predictions and experimental data for both TPA and IND dyes confirms the reliability of the computational methodologies employed. These findings endorse TPA2 and IND2 as promising candidates for advancing the DSSCs efficiency.</p></div>","PeriodicalId":720,"journal":{"name":"Optical and Quantum Electronics","volume":"57 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142976659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
