The development of third-generation photovoltaic (TGPV) technologies promises to address some of the limitations of conventional silicon-based solar cells. However, the scalability of these technologies is a critical factor in their practical application. TGPV include Perovskite Solar Cells (PSC), Organic Solar Cells (OSC), and Dye-Sensitized Solar Cell (DSSC). This paper reviews and summarizes the recent trends and research on the deposition techniques and modularity of TGPV. Various deposition techniques such as slot-die coating, thermal evaporation, and spray pyrolysis are discussed, along with their advantages and limitations. Modularity, which allows for the integration of TGPV cells into different structures, is also examined as a critical factor in scalability. The paper concludes that the scalability of TGPV technologies depends on the development of efficient and cost-effective deposition techniques and modularity, which will facilitate the integration of the TGPV cells into various structures and enable the widespread use of these promising technologies. © Published under licence by IOP Publishing Ltd.

Stemphylium vesicarium (Wallr.) Simmons is a plant pathogenic fungus causing purple spot in both fern and spears of asparagus (Asparagus officinalis L.). Although the fern can be sprayed with fungicides to control the disease, pesticide applications during spear harvest are restricted. Infected spears can develop prominent pigmentation at lesion sites, reducing marketable yield. Breeding resistant asparagus cultivars with decreased lesion numbers and reduced purpling at the site of infection is considered the most economical and sustainable approach to combat this disease. The objectives of this study were to determine the genetic architectures of, and relationships among, anthocyanin pigment expression in spear scale leaves (ALS) and spear lesions (APS) and purple spot levels in spears (NPS) and fern (PSF). Traits were phenotyped over 2 years under natural conditions in an F₁ pseudo-testcross population, and quantitative trait loci (QTL) were mapped. ALS, APS, NPS, and PSF were not correlated, suggesting independent regulation of the anthocyanin pathway in scale leaves and lesions and no relationship between pigment and disease. Segregation, 3 red:1 purple and 3 red:13 purple, was observed in scale leaves and lesions, respectively. Two stable QTL for each of ASL, APS, and NPS, one tentative QTL for ASL, four tentative QTL for APS, two tentative QTL for NPS, and three tentative QTL for PSF were identified. Candidate genes were found for four loci. This study advances the genetic understanding of anthocyanin pigmentation at a tissue-specific level, and purple spot disease severity in spears and fern, supporting future breeding efforts. © 2025 The Author(s).

The emergence of two-dimensional (2D) MXenes as efficient light-to-heat conversion materials offers significant potential for solar-based desalination, particularly in photothermal interfacial evaporation, enabling cost-effective solar-powered membrane distillation (MD). This study investigates solar-powered MD afforded by a photothermally functionalized spacer, which is built by spray-coating Ti3C2Tx MXene sheets on metallic spacers. 2D Ti3C2Tx MXene gives an ultrahigh photothermal conversion efficiency;thereby, by Ti3C2Tx MXene-coated metallic spacer, this rationally designed spacer allows for a localized photothermal conversion and interfacial feed heating effect on the membrane surface, especially for MD operation. As a feed spacer and a photothermal element, Ti3C2Tx MXene-coated metallic spacer exhibited stable enhanced water flux of up to 0.36 kg·m−2h−1 under one sun illumination for a feed salinity of 35 g·L−1, corresponding energy conversion efficiency of 28.3 %. Overall, the developed photothermal Ti3C2Tx MXene-coated spacers displayed great potential in enhancing the performance, scalability, and feasibility of solar-driven MD process, paving the way for further development of photothermal elements that can be implemented in solar MD applications. © 2024 Elsevier Ltd

Water pollution by per- and poly-fluorinated alkyl substances (PFAS) has become a major concern that needs to be dealt with immediately. In this study, a novel, continuous-flow, liquid-phase plasma discharge reactor (CLPD) was evaluated for its effectiveness and efficiency in removing PFOA in water. Argon was used as the carrier gas to evaluate other operating parameters including gas flow rate, water flow rate, water conductivity, and power applied using a two-level partial factorial design. The results showed that gas flow rate was the most significant factor among the four factors affecting the removal efficiency of PFOA by CLPD (p = 0.0029). The best combination of the four operating parameters was obtained (conductivity = 300 µs/cm, water flow rate = 150 mL/min, gas flow rate = 1.5 sL/min, and power = 100 W), under which the CFLPPD could achieve a PFOA removal rate of 93.4%. The breakdown pathway was estimated to be from PFOA to PFHPA, to PFHXA, to PFHeA, to PFBA, and then to H2O, CO2, F, and short-chain organics. © 2023 ASABE Annual International Meeting.

The potential for future energy crises is a problem the world is currently facing. Many countries are switching from fossil to renewable energy to prevent an energy crisis. One of the most developed renewable energy today is solar energy. Easy installation makes solar energy installation not only on a large scale but also on a home scale. Urban areas will be very suitable for building solar photovoltaic (PV) roofs due to minimal open areas. In installing rooftop solar PV, sound planning is needed to predict the energy potential that can be provided by solar energy on the rooftop of a building. Spatial modeling can be done to determine the energy potential and suitable location for rooftop solar PV installation. In building rooftop solar PV modeling, the level of detail of the building will affect the results of the model. The rooftop's shape and the building's height will affect the amount of solar radiation going into the building. However, the higher the level of detail of the building, the higher the cost and processing time will be. This study will review the differences in modeling the potential of rooftop solar PV using different levels of detail. This research will integrate solar radiation data from remote sensing to determine the energy potential of solar radiation and digital surface model data from photogrammetry to create a level of detail for buildings. Integration of solar radiation data and the level of detail of the building will use hillshade analysis. Hillshade analysis can review the shadow effect on the rooftop of a building which will be directly related to the potential of solar energy on the rooftop of the building. This study determines the energy potential on the rooftop of the building with different levels of detail, namely 0, 1, and actual shape, to determine the difference in energy potential in the three scenarios. Hopefully, this research will determine the best level of detail for modeling rooftop solar PV. The best model that can sho

A simple one-step solvothermal approach has been adopted for the synthesis of SnS2. SEM shows hierarchically SnS2 with petal-like 3-dimensional layer structures because of this process. In this investigation, the as-prepared electrode material have an excellent specific capacitance of 721F g−1 at 1 mVs−1, indicating extraordinary performance. The improved electrochemical performance is because to unique ultrathin petal discrete structure, which provides increased electrolyte/electrode interface, high active sites, rapid ion/electron transfer, and short diffusion distances. A manufactured symmetric solid-state supercapacitor (SSC) device also has a large capacity to operate commercial LEDs, which allows for the assessment of its practical applicability in device-level application. According to the findings of this work, suitably layered 3D SnS2 electrode materials could be a promising route for the development of environmentally friendly energy storage applications. © 2022

Macroalgae are vital components of blue carbon ecosystems, yet their elemental compositions in the Red Sea are not well understood. This study analyzed 22 elements in 161 macroalgae blades from 13 species in the Saudi Arabian Red Sea. Macroalgae from coral reefs had higher K, As, and Sr but lower TN (Total nitrogen), Na, Mg, Al, P, S, Cr, Mn, Fe, and Zn compared to those from seagrass meadows, likely due to proximity to human activities. In the Southern Red Sea, macroalgae showed lower Sr but higher TOC (Total organic carbon), TN, P, and Cd compared to the North, suggesting nutrient inflows from the Indian Ocean. Macroalgae blades have lower carbon sequestration capacity than seagrass and mangrove leaves but are more effective bioindicators of metal pollution. Halymenia sp., Caulerpa taxifolia, and Dyctiota sp. showed the highest TOC, TN, and P contents among red, green, and brown macroalgae, highlighting their role in carbon sequestration and nutrient cycling. Amphiroa fragilissima, Udotea flabellum, and Padina sp. emerged as promising metal pollution bioindicators. Macroalgae from Al Birk, Al Lith, Thuwal, Yanbu, and Al Wajh exhibited alarming Cr (~10.9 mg kg−1) and Ni (~27.2 mg kg−1) levels, exceeding toxicity thresholds, urging stringent pollution control measures. © 2024, The Authors.
