In this study, we investigated the performance of a solar cell with a general configuration of FTO/ETL/PbS/P3HT/Au using SCAPS-1D simulation software (version 3.3.10). Several electron transport layer (ETL) materials, including TiO<sub>2</sub>, ZnO, tungsten disulfide (WS<sub>2</sub>), tin (IV) oxide, and buckminsterfullerene (C<sub>60</sub>), were initially tested. After optimization, WS<sub>2</sub> was identified as the best ETL material, exhibiting a power conversion efficiency (PCE) of 4.91 %. Subsequently, the WS<sub>2</sub>-based device architecture was used to test various hole transport layer (HTL) materials, including organic materials like poly(3-hexylthiophene) (P3HT) and 2,2′,7,7′-Tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9′-spirobifluorene (spiro-OMeTAD), as well as inorganic materials such as CuSCN, Cu<sub>2</sub>O, and copper zinc tin selenide (CZTSe). Among the HTLs tested, CZTSe exhibited the highest PCE of 13.47 %. The ideal defect density for each device was maintained at 1.0 × 10<sup>14</sup> cm<sup>−3</sup>. Furthermore, a bifacial version of the device, Ag/FTO/WS2/PbS/CZTSe/Au, was simulated, showing a bifacial factor (BF) for PCE of 81.74 % and a bifacial gain (BG) of 81.89 %. Based on the simulation results, we predict that the PbS-based bifacial solar cell can achieve a PCE greater than 24 %, demonstrating its potential for high-efficiency solar energy conversion. This study systematically optimized both the electron and hole transport layers in PbS-based bifacial solar cells, demonstrating the potential of WS<sub>2</sub> as an effective electron transport material and CZTSe as a promising hole transport material for achieving high-efficiency performance.</div></div>","PeriodicalId":21151,"journal":{"name":"Results in Optics","volume":"19 ","pages":"Article 100818"},"PeriodicalIF":0.0,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143769146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These systems typically employ Fresnel lenses to focus infrared signals onto pyroelectric detectors, thereby enhancing detection range and differentiating between dynamic objects and background noise. However, conventional coaxial Fresnel lens designs are hindered by uneven light intensity distribution, resulting in reduced sensitivity and non-uniform detection across the field of view. This paper presents a breakthroughnon-coaxial Fresnel lens architecturethat addresses these limitations through advanced optical design and optimization techniques. By redistributing infrared radiation uniformly across the sensor’s surface, the proposed design significantly enhances detection uniformity and sensitivity. The methodology leveragesadvanced ray tracing and optical simulation tools(Zemax Optics Studio) in both sequential and non-sequential modes to optimize key performance parameters such as light uniformity, focusing efficiency, and aberration minimization. The results reveal that the optimized Fresnel lens achieves superior performance in small-angle, high-gain, and short focal length applications, offering unprecedented consistency in motion detection.
