These cells capture sunlight and indoor lighting, combining energy efficiency with aesthetic appeal, and address the growing demand for off-grid power sources for IoT devices. Organic solar cells (OSCs) are especially suitable for indoor use due to their lightweight nature, low toxicity, cost-effectiveness, and customizable colors based on their photoactive materials. However, color tuning and material variability pose challenges to scalability. This study incorporates a color filter (CF) based on a metal-dielectric-metal structure to enhance OSC performance. Using silver (Ag) for electrical conductivity and tin oxide (SnO₂) for optical transparency, the CF optimizes light transmission and charge transport. Conventional photoactive materials, P3HT and PCBM were employed, and simulations using MATLAB and SCAPS-1D analyzed optical and electrical properties. This approach offers promising advances for sustainable indoor energy solutions.</div></div>","PeriodicalId":21042,"journal":{"name":"Results in Physics","volume":"70 ","pages":"Article 108172"},"PeriodicalIF":4.4,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143512261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is in this light that recurrent neural networks are well suitable for use in complex areas including fluid dynamics, biological computing, and biotechnology since they are capable of learning patterns. In this study we examine the ability of Levenberg-Marquardt algorithm with recurrent neural networks (LMA-RNNs) in simulating the MHD heat transfer properties of nanofluid consisting of carbon nanotubes model via porous media in terms of thermal conductivity. In the contemporary era SWCNTs and MWCNTs based nanofluids have many applications in drug delivery, cancer treatment, tissues regeneration, mechanical engineering, optical devices, electrically powered devices, and industrial production, particularly in solar thermal systems where heat transfer performance can boost energy capture and storage efficiency. The data used in this study is collected using Adams numerical technique and is then fine-tuned using the LMA-RNNs. The LMA-RNNs is performed with 80% of data to train the model and another 10% is used to test the model and the left over 10% is used for validation. In terms of plots for SWCNTs and MWCNTs further information is provided regarding the impacts of critical physical aspects on the field of velocity and temperature, and from the results presented in this article it is observed that an increase in suction parameter leads to a decrease in velocity and temperature profiles. It is found that increase in the form of higher Eckert number, it can come to an abstraction that the temperature profile increases as well. Furthermore, it is noticed that higher Pr values lead to lower values of thermal diffusivity, which mean that the thermal layer is thinner, or that there is less diffusivity of heat. For the assessment of the performance of the applied LMA-RNNs, the fitness of mean squared error, regression plots and error distribution in histograms is presented. The reduced MSE reveals that predictions of model are less likely to deviate from the true values and are more accurate this validates the proposed approach.</div></div>","PeriodicalId":21042,"journal":{"name":"Results in Physics","volume":"70 ","pages":"Article 108175"},"PeriodicalIF":4.4,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143562188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sensitivities of the coupled modes increase as the two defect layers get closer and the threshold distance of dual defect layers for using the advantage of coupled modes is determined in the paper. The sensitivities and Q factors of these two coupled modes are different in most conditions which highlights the potential of utilizing one of the coupled modes with higher sensitivity for sensing applications of the specific material. Furthermore, accurate and real-time measurements of the analyte refractive index are possible with these coupled modes.

We present a gas sensor designed to detect H₂S in varying concentrations using a Weyl semimetal (WSM) combined with a one-dimensional porous silicon photonic crystal (PSi-1DPC). In our sensor, the gas is contained in the cavity formed between the WSM layer, which serves as a plasmonic material, and the PSi-1DPC. The sensor utilizes Tamm plasmon polaritons (TPPs) generated at the interface of the WSM and PSi-1DPC to detect minute changes in H₂S concentration. We investigate the impact of the geometrical parameters of the sensor and the intrinsic characteristics of the WSM layer on its efficiency to identify the optimal structure.

By incorporating PDI-C8, a heterostructure is formed, enhancing visible light absorption and resulting in improved visible light sensing performance. Multiple material analyses also reveal that the organic PDI-C8 is stacked nearly vertically on the ZnO NRs, forming an organic layer with internal voids. As the amount of organic material increases, bubble-like microstructures may form on the surface. Furthermore, an appropriate heterojunction between ZnO and PDI-C8 facilitates broadband light sensing. Experimental results show that pure ZnO-NRs devices exhibit UV photosensing only, whereas ZnO-NRs devices with 1 drop of PDI-C8 exhibit strong blue and green light responses, and those with 3 drops of PDI-C8 demonstrate an improved red light response.
