In this study, we investigate a two-step approach involving the simulation of both a perovskite-based single-junction solar cell and a tandem structure incorporating silicon layers, using Silvaco TCAD tools. Initially, a single-junction perovskite solar cell with the configuration FTO/TO₂/MAPbl₃/HTM was simulated. The simulation results showed a short-circuit current density <i>J</i>_sc of 20.057 mA/cm², an open-circuit voltage <i>V</i>_oc of 1.15 V, a fill factor (FF) of 50.03%, and a power conversion efficiency (PCE) of 12.68%. These values were compared with experimental data obtained from an external laboratory <i>J</i>_sc = 20.63 mA/cm², <i>V</i>_oc = 0.96 V, FF = 66.41%, and PCE = 13.15%), highlighting the alignment and deviations between the simulation and physical measurements. To enhance the performance, a tandem structure was developed by incorporating a 3-nm FTO layer as an intermediate contact beneath the HTM layer, followed by a three-layer silicon subcell consisting of donor (n-type), intrinsic, and acceptor (p-type) layers, resulting in significantly improved parameters, with <i>J</i>_sc reaching 36.5 mA/cm², <i>V</i>_oc of 1.05 V, FF of 73.18%, and a PCE of 28.03%. Additional studies were conducted to evaluate the effect of varying the thickness of the intrinsic silicon layer on the device performance and to analyze the temperature-dependent behavior of the tandem structure, providing insights into its stability and operational adaptability. This work underscores the potential of tandem architectures, particularly perovskite–silicon combinations, in advancing photovoltaic efficiency.</p></div>","PeriodicalId":626,"journal":{"name":"Journal of Electronic Materials","volume":"54 10","pages":"8618 - 8627"},"PeriodicalIF":2.5,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145122029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this present work, we explore the effects of SWCNT nanostructure over water diffusion and the influence of system temperatures and flow rates on bond dynamics. For molecular mechanics, we have performed molecular dynamics (MD) simulations and found that water diffusion increases linearly with an increase in temperature, but a very slow increment is observed at varying flow rates. Using the radial distribution function (RDF), we have revealed that the SWCNTs lead to an improvement of clustered structures and enhanced water diffusion for varying flow rates. The obtained diffusion coefficients have been found to be in good agreement with previously reported MD simulation data, validating the accuracy of the current computational approach.
