    Cuce, Pinar Mert; Guclu, Tamer; Cuce, Erdem; Bouabidi, Abdallah; El Hadi Attia, Mohammed

    This study experimentally investigates the thermal and electrical performance, economic feasibility, and environmental impacts of a hybrid energy system integrated with a parabolic trough collector (PTC) and thermoelectric generator (TEG). In the established system, solar energy is converted into electrical and thermal energy using a steam turbine and TEG. Experimental data indicate that the system operates with an average efficiency of 71.44%, which varies depending on the intensity of solar radiation. The overall energy efficiency of the system is calculated as 14.51%. In the economic analysis, the payback period of the designed system is approximately 5.4 years, while the levelised cost of energy production (LCOE) is calculated to be 0.075 USD kWh−1. The environmental assessment indicates that the system can prevent 356.18 kg of CO2 emissions annually and save approximately 1499.72 L of water. These findings demonstrate that hybrid systems offer an economically and environmentally sustainable and efficient alternative to energy production.

    A novel passive cooling configuration for photovoltaic panels based on bio-inspired heatsinks and nanoparticle-enhanced PCM

    Cuce, Erdem; Cuce, Pinar Mert; Guclu, Tamer

    This study presents the design, fabrication, and experimental evaluation of a novel passive thermal management system for photovoltaic (PV) modules that integrates a bio-inspired aluminium heatsink with a nanoparticle-doped phase change material (PCM). The proposed configuration aims to regulate the temperature of the PV module under real outdoor conditions without any external energy input. The bio-inspired heatsink was designed based on coral-like branching geometry to enhance natural convection and heat distribution within the PCM. The PCM, doped with metal-oxide nanoparticles (Al2O3, SiO2, TiO2) at a 2% mass fraction, provided additional latent-heat storage capacity and improved thermal conductivity. Experimental tests were conducted using two identical monocrystalline PV panels. The results demonstrated that the bio-inspired-cooled PV module effectively reduced surface temperature fluctuations by 8–15 °C and achieved a maximum efficiency improvement of 9.2% compared to the uncooled configuration. The integration of the PCM layer with the bio-inspired heatsink maintained a more stable operating temperature throughout the day, particularly during high-irradiance conditions. Hourly I-V and P-V analyses confirmed that the hybrid module consistently exhibited higher maximum power and efficiency values. Furthermore, the estimated energy yield analysis revealed that the average efficiency gain of 5.6% achieved under outdoor conditions could lead to a substantial increase in annual energy production. Overall, the hybrid bio-inspired fins + PCM system offers a sustainable, self-regulating, and energy-free cooling solution that enhances both the performance and durability of PV modules.

    Bio-inspired passive cooling of photovoltaic modules using Sphagnum palustre moss: An experimental study

    Cuce, Pinar Mert; Abay, Gökhan; Cuce, Erdem; Guclu, Tamer; Alvur, Emre

    This study investigates the potential of Sphagnum palustre moss as a completely natural, passive evaporative cooling medium for photovoltaic (PV) modules. Unlike synthetic hydrogels or complex biomimetic structures, the proposed system utilises the innate porous structure and high water-retention capacity (up to 20 times its dry weight) of natural moss to facilitate rapid heat dissipation. Experimental evaluations conducted under effective solar irradiances of 510.4–820.9 W/m2 demonstrate that the moss-cooled configuration achieves a remarkable temperature reduction of 27.4–39.8 °C compared to uncooled standalone panels. These thermal improvements translate into relative power gains of 6.10% to 11.66% and an exceptional evaporative cooling power of up to 598 W/m2. The results establish Sphagnum palustre as a highly effective, biodegradable, and low-cost alternative for PV thermal management, offering performance competitive with advanced engineered cooling materials whilst ensuring long-term environmental sustainability.

    Experimental 4E analysis (energy-exergy-economic-environmental) of hybrid parabolic trough collector-thermoelectric generator-phase change material cogeneration system

    Guclu, Tamer; Cuce, Pinar Mert; Cuce, Erdem

    Hybrid solar cogeneration systems are critical for enhancing energy utilisation and mitigating the intermittency of solar resources. This study presents a comprehensive 4E (Energy-Exergy-Economic-Environmental) experimental analysis of a novel hybrid system that uniquely integrates a Parabolic Trough Collector (PTC), a small-scale steam turbine, a Thermoelectric Generator (TEG) assembly, and a Phase Change Material (PCM) thermal storage unit. The system's performance was investigated under 15 distinct operating conditions, varying initial water masses (0.1, 0.15, 0.2 kg) and operating pressures (6, 8, 10, 12, and 14 bar). Experimental results demonstrated the system's adaptive cogeneration capabilities. At 14 bar and 0.2 kg, the system achieved its maximum Solar-to-Electricity efficiency of 0.42%. At this operating condition, the highest collector thermal efficiency was 25.25% (at 6 bar), and the maximum overall energy and exergy efficiencies were 8.43% and 1.45%, respectively. A key finding was the system's adaptive electrical output: at low pressures (6 bar), the TEG acted as a crucial co-generator, supplying up to 55% of the electricity, whereas at high pressures (14 bar), the turbine dominated, accounting for 88-90% of the output. Furthermore, the study experimentally confirmed that latent heat transfer was the dominant heat transfer mechanism for the PCM, with latent heat contributing ∼445 kJ (55%) of the 805 kJ total energy stored. The thermo-economic analysis confirmed the system's viability, yielding a Simple Payback Period (Spp) of 6.9 years and a competitive Levelised Cost of Energy (LCOE) of $0.101/kWh. The system is projected to save 118.8 kg of CO2 and 660 L of water annually. The results validate the thermodynamic and economic feasibility of the integrated PTC-Turbine-TEG-PCM concept as a flexible solution for small-scale solar cogeneration.

    Life cycle cost and carbon footprint analysis of CuO–Al2O3/water hybrid nanofluids in thermoelectric vaccine refrigerators

    Cuce, Pinar Mert; Guclu, Tamer; Cuce, Erdem

    This study investigates the application of a CuO–Al2O3/water hybrid nanofluid as a coolant in thermoelectric vaccine refrigerators, aiming to enhance heat dissipation from the Peltier module’s hot side. A 35-L cooling cabinet was utilised, and experimental comparisons were made using water and a 2% CuO–Al2O3/water hybrid nanofluid. Results show that the vaccine cabinet reaches the target temperature of 4 °C in 990 s with nanofluid, compared to 1200 s with water. The system’s energy consumption was reduced by 18.3%, and carbon emissions decreased by 12.3% over a 15-year lifespan, highlighting its environmental benefits. Despite similar coefficients of performance (COP), the nanofluid system demonstrates enhanced efficiency, shorter cooling times, and long-term sustainability advantages. These findings support the adoption of hybrid nanofluids in thermoelectric cooling applications for energy-efficient and environmentally friendly refrigeration systems.

    CFD and solar water collector

    Guclu, Tamer; Cuce, Pinar Mert; Cuce, Erdem

    Increasing environmental pollution on a global scale and the rapid depletion of traditional energy sources have led scientists to search for clean and renewable energy sources. Among renewable energy sources, solar energy stands out as a clean, energy-efficient and abundant source. There are many methods of obtaining thermal and electrical energy from solar energy. Among these methods, solar water collectors are widely used throughout the world, thanks to their wide range of applications, from domestic hot water supply and space heating applications to industrial process heat. The main purpose of this study is to examine solar water collector systems in a general framework. Solar water collector types are introduced in detail, their performance is evaluated, and especially CFD studies on their thermal efficiency are presented. Solar water collector systems were examined comparatively in terms of energy efficiency and the parameters affecting their thermal performance were observed. As a general acceptance, evacuated-tube solar water collectors are more efficient than flat-plate collectors. Compound parabolic collectors are preferred in higher-temperature applications. Thermal efficiency can be increased by using nanofluids or hybrid systems.

    Smart and Sustainable Energy Systems

    Guclu, Tamer; Cuce, Pinar Mert; Cuce, Erdem

    Today, fossil fuels still have a more important share in energy production. Reducing the share of these resources in energy production is an extremely important issue in order to prevent the environmental effects caused by greenhouse gas emissions. Especially in the last ten years, the transformation into smart and sustainable energy systems has accelerated in order to use energy resources efficiently and to reduce greenhouse gas emissions. Smart energy systems are systems that allow the use of renewable energy sources such as solar, wind, and geothermal instead of a fossil fuel-based large production system. Thanks to these systems, instead of a single large power generation facility, energies produced from renewable sources close to the area of use can be integrated into the system, thus reducing greenhouse gas emissions. In addition, smart energy systems are effective in reducing energy costs, as they make final consumers a part of energy production. In addition, since smart energy systems allow the integration of sectors such as electricity, heating, energy, transportation, and transmission, they provide a sustainable, accessible, economical, clean, and efficient energy supply. In this study, information about smart and sustainable energy systems has been given, advantages and difficulties have been mentioned, and also an economic evaluation has been made.

    Design, modelling, environmental, economic and performance analysis of parabolic trough solar collector (PTC) based cogeneration systems assisted by thermoelectric generators (TEGs)

    Cuce, Pinar Mert; Guclu, Tamer; Cuce, Erdem

    Concentrating solar power systems (CSP) is a very efficient technology for clean and renewable energy production. It basically works on the principle of focusing the sun's rays with the help of a reflective surface. There are two types of CSP systems: point-focused and line-focused. Point-focused ones are parabolic dish collectors and solar towers. Line-focused ones are parabolic trough collectors (PTCs) and linear Fresnel reflectors. It is possible to reach focus temperatures over 1000 °C with point-focused CSPs. Line-focused CSP systems are used to obtain thermal and electrical energy at temperatures below 500 °C. Among CSP technologies, PTCs are widely preferred. While it can be used alone, it can also be used in combination with other power generation systems by creating hybrid systems. In this regard, hybrid PTC/TEG energy systems created with thermoelectric generators (TEGs) come to the fore. These systems have higher electrical and thermal efficiency values compared to traditional PTCs. In this study, CSP systems, PTCs, TEGs and hybrid solar energy systems-based PTCs were examined in detail. It is concluded from the study that the total thermal efficiency of PTC-TEG hybrid systems can be enhanced by up to %70 with respect to PTC systems.
