A solar laser pumping approach to achieve both simultaneous and stable multibeam solar laser operation under solar tracking error condition is proposed here.

Zemax® and LASCAD™ analysis demonstrate that four simultaneous and stable 1064-nm continuous-wave solar laser emissions with similar multimode power levels can be achieved even with azimuthal solar tracking errors up to ± 0.5 deg. The variation on the multimode solar laser power of the four rods is significantly reduced from 32.38% and 55.52% without the homogenizer to 0.00% and 0.21% with the homogenizer for ± 0.1 deg and ± 0.2 deg azimuthal solar tracking error, respectively. More importantly, simultaneous and stable TEM00 mode solar laser emissions from the four rods are also numerically attained under solar tracking error condition.","PeriodicalId":16781,"journal":{"name":"Journal of Photonics for Energy","volume":"13 1","pages":"028001 - 028001"},"PeriodicalIF":1.7,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49076821","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}

Relatively low conversion efficiency is the main limitation for realizing the conversion from CO2 photoreduction to high-value-added chemicals. Herein, we demonstrate that coupling alternating magnetic field (AMF) can significantly enhance the solar-catalyzed CO2 conversion process. Utilizing NiO / TiO2 as the experimental photocatalyst, CO2 could be reduced into CH4 with the participation of water vapor. The catalytic system presents a high activity that is improved by ∼200 % toward CH4 production through integrating with AMF. The applied AMF, on one hand, can increase the density of carries by restraining the combination of photogenerated electron-hole pairs. On the other hand, the applied AMF enhances the oxidizability of the catalysts with simulated solar irradiation to boost the oxidation of H2O to O2. Further, our examination illuminates that the Ni species serve as the adsorption/mobilization sites of CO2 to boost the conversion of CO2 to CH4 by photogenerated e − and the H + produced by H2O. This strategy paves a new path for boosting photocatalytic CO2 conversion by integrating AMF into the reaction.","PeriodicalId":16781,"journal":{"name":"Journal of Photonics for Energy","volume":"13 1","pages":"026501 - 026501"},"PeriodicalIF":1.7,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41727811","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}

Detailed optoelectronic simulations of thin-film photovoltaic solar cells (PVSCs) with a homogeneous photon-absorber layer made of with CIGS or CZTSSe were carried out to determine the effects of defect density, minority carrier lifetime, doping density, composition (i.e., bandgap energy), and absorber-layer thickness on solar-cell performance. The transfer-matrix method was used to calculate the electron-hole-pair (EHP) generation rate, and a one-dimensional drift-diffusion model was used to determine the EHP recombination rate, open-circuit voltage, short-circuit current density, power-conversion efficiency, and fill factor. Through a comparison of limited experimental data and simulation results, we formulated expressions for the defect density in terms of the composition parameter of either CIGS or CZTSSe. All performance parameters of the thin-films PVSCs were thereby shown to be obtainable from the bulk material-response parameters of the semiconductor, with the influence of surface defects being small enough to be ignored. Furthermore, unrealistic values of the defect density (equivalently, minority carrier lifetime) will deliver unreliable predictions of the solar-cell performance. The derived expressions should guide fellow researchers in simulating the graded-bandgap and quantum-well-based PVSCs.","PeriodicalId":16781,"journal":{"name":"Journal of Photonics for Energy","volume":"13 1","pages":"025502 - 025502"},"PeriodicalIF":1.7,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44454089","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}

It is essential to study the thermal dewetting behavior of as-deposited nano-films for large scale and high-throughput fabrication. We report here on the nucleation of Au nanostructures onto titanium dioxide (TiOx) thin films surfaces, which occurred in consecutive steps. First, TiOx thin films were grown on quartz substrates reactively by e-beam evaporator and then thermally annealed at different temperatures, starting from 300°C to 900°C. Subsequently, a nano-film of Au was deposited on the top of these TiOx surfaces. The stacked Au / TiOx samples were post-annealed using muffle furnace at a temperature of 600°C for 1 h, to study the thermal dewetting properties and the controlled growth of the different TiOx morphologies on the formation of Au nanoparticles (NP) and their plasmonic response. Such dual-structures were characterized accordingly to probe their topological, morphological, structural, and optical properties, by means of x-ray photoelectron spectroscopy, scanning electron microscope, atomic force microscopy, and ultra-violet–visible–near infrared characterization techniques. The thermal dewetting properties were found to improve at high temperatures (>500 ° C), where the Au NP size distribution was found to follow a Gaussian pattern centered around 30 nm. The average surface roughness also increased significantly with respect to the TiOx dewetting temperature, which is mainly attributed to the porosity of the films. Finally, the absorption peak for Au nanostructures has shown a localized surface plasmon resonance close to 520 nm, along with a broad shoulder peak with a strong tail thereby reflecting the wide distribution of the formed Au NP sizes.","PeriodicalId":16781,"journal":{"name":"Journal of Photonics for Energy","volume":"13 1","pages":"025501 - 025501"},"PeriodicalIF":1.7,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43412346","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}

The rearrangement of a photovoltaic array (PVA) plays a key role in its power output subjected to partial shading situations (PSSs). Achieving maximum power output under PSSs is a significant parameter to decide the best topology for the PVA framework (PVAF). An odd-even sudoku framework (OESF) for the total cross-tied (TCT) array that augments the resultant power production is proposed. OESF is designed in such a way that the PV modules (PVMs) are rearranged in a particular pattern within the TCT array without altering the electrical connections. The comparative performance analysis of the reconfigured OESF is done with those of the existing PVAFs. The extent of mismatch power losses (MPLs) abruptly affecting the performance of PVAs is studied under PSSs and the results are analyzed. The results show that as compared to the other frameworks, the proposed OESF can minimize the MPLs and subsequently enforce significant improvement in the global maximum power point, fill factor (FF), and efficiency (EF). The different PSSs are considered for the study and the observations show that the MPL in case of OESF is 6.64%, which validates that there is reduction in the power losses displayed by OESF reconfiguration, in contrast to other frameworks considered. Further, the maximum values of FF and EF for OESF are 52.40% and 13.83%, respectively, signifying a considerable enhancement in both the values through the proposed technique.","PeriodicalId":16781,"journal":{"name":"Journal of Photonics for Energy","volume":"13 1","pages":"015502 - 015502"},"PeriodicalIF":1.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46126381","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}

Conventional electricity distribution using copper wires is well established due to its high efficiency. However, recent research and development on power-over-fiber (PoF) has proposed optical fiber as an alternative to copper wire as the transmission medium for electricity distribution. The research and development on PoF technology have gained significant momentum over the past decade due to its advantage over copper cables in providing electrical isolation and reducing space in remote sites. The technological advances in laser diodes, fiber optic cable fabrications, and semiconductor manufacturing contribute to developing an efficient PoF system, making them more commercially viable. This paper reviews various PoF systems that imply different arrangements of high-power lasers, fiber optic cables, and photovoltaic power converters. The PoF systems are made available for various applications such as in-home applications, smart power management, and powering sensors with bidirectional communications. The comparison of the PoF composition, commercialized PoF systems, and patented PoF systems are also comprehensively discussed. Finally, the challenges in implementing PoF systems are highlighted, as well as future prospects for research and applications. The information reviewed in this paper aims to provide a roadmap for developing a future PoF system with improved power conversion efficiency.","PeriodicalId":16781,"journal":{"name":"Journal of Photonics for Energy","volume":"13 1","pages":"011001 - 011001"},"PeriodicalIF":1.7,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47652263","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}
