This study investigates the use of nanofluid-cooled Thermoelectric Generators (TEGs) integrated with a Photovoltaic (PV) panel to enhance overall energy efficiency system. Three cooling fluids — Water (W), CuO/W single Nanofluid (NF), and CuO-Fe/W hybrid NF are examined at various flow rates for PV panel. The research studies PVT-TEG-NF system considering both normal concentrated solar irradiation in 3D parallelly-cooled heat sink setup comparing its electrical thermal performance, which has not been previously addressed literature. results demonstrate that by utilizing CuO-Fe/W, temperature 935 W/m2 summer can be maintained 31.7 °C, is 8.8 % 13 lower than those achieved using water, respectively. For 0.08 m/s inlet velocity, total output power PV-TEG about 9.5 W, removal rate ∼37.2 W. Additionally, compared combined (the ratio input) increases from 66.7 76.7 %.

Solar energy has emerged as a standout alternative among the various types of renewable energies due to availability and minimal upfront expense in conversion. One most comprehensive methods utilize solar potential is photovoltaic (PV) systems that apply phenomenon called "photovoltaic effect". However, one major obstacle widespread use PV their optimal working temperature. The performance based on heat distribution surface panel need be decreased. From previous literature reviews cooling, it found there's insufficient attention given discussing vital standardized parameters necessary for evaluating efficiency cooling techniques systems. Hence, this article, several updated studies technology are discussed including passive, active combined cooling. Besides that, assessment also elaborated temperature-dependent difference factor (FTDED), temperature dependent power (FTDPD), (FED), ratio (R), cooler lifespan efficacy (FLSE), production cost effectiveness (FCE), modified (FMCE), area (FCAE). It was some challenges addressed future cost, maintenance requirement, consumption especially under extreme conditions. recommendations purpose tackling these challenges.

A photovoltaic (PV) cell is very sensitive to temperature changes where decreasing plays the main role in increase of PV electrical efficiency and output power. Therefore, researchers used different techniques for cooling modules avoid immoderate heating decrease panel temperature, resulting raising power output, energy efficiency, performance, life panel. In present work, panels are cooled by forced convection. Cooling airflow characteristics distribution examined using computational fluid dynamics (CFD). order evaluate CFD predictions, experimental measurements obtained a sunny day on 23rd September 2021 period from 10 AM 4 PM. The performed three arrangements panels. uncooled was considered as reference case. Two methods were examined: with air-cooling lower duct supplying air blower, small fans arranged symmetrically backside temperatures determined calculations compared experimentally measured it found be good agreement. results showed that can enhance performance achieve maximum total 2.1% 7.9% saving energy. Using blower technique achieves 1.34% 4.2%

A small percentage of the energy from solar radiation is converted into electricity by photovoltaic module, while rest lost as heat. This heat causes module's temperature to increase effecting its performance and decreasing efficiency. To address this problem, a phase change material cooled 20 Watt module was analyzed improve efficiency absorbing store it sensible latent during day. The traditional method typically tends seal panels rare back fill with for cooling. In study, six containers filled that are easy assemble disassemble employed instead single container in which makes application more technical applicable. has several advantages over previous approaches. It allows convenient adjustment effectively adapt weather fluctuations. Furthermore, when inside completely dissolved, itself can be easily replaced, thereby improving cooling process enhancing system throughout Moreover, tackle issue leakage been persistent problem many studies Additionally, they offer advantage reducing required amount eliminating need entire system. goal study reevaluate passive using investigate effect these being appropriate inappropriate properties on module. measurements were taken three sensors at different locations without modules. experimental results reveled reduce average 10 °C, enhance power 5.23% compared non-cooled panel period measurement. showed negative impact 3 W
