The incident solar energy that impinges upon the photovoltaic cells undergoes a conversion process, resulting in generation of electrical and absorbed into heat. This increase temperature adversely affects performance panel, leading to decrease its overall efficiency. study examines properties phase change materials, specifically paraffin wax, natural beeswax, combination wax comparison panel lacking any substance. experiment was conducted climatic conditions Iraq, namely city Hawija, located southwest Kirkuk, during summer 2022. prevailing environmental throughout this period averaged 44 °C. involved comparing plate temperature, power, results indicated all materials caused board at beginning for short duration. Nevertheless, as material (PCM) melting, dissipation heat becomes unfeasible, gradual temperature. It observed there rise afternoon hours. According recorded data, use beeswax resulted by 4 °C reference did not incorporate (PCM). Additionally, efficiency (PV) system increased 1% when compared PV Compared with (reference). ranged from 13% 14%. findings, integration phase-change panels has been effectively lower panels, hence enhancing their Consequently, approach represents viable advantageous choice.

The integration of photovoltaic/thermal (PV/T) systems, which enable the simultaneous conversion solar energy into both electricity and thermal energy, holds great promise in solar-rich northwest region China. This study aims to assess performance a micro heat pipe (MHP) PV/T system through comprehensive experiments conducted over four seasons Lanzhou. experimental setup involved measurement various parameters including environmental temperature, surface temperature panel, back water as well determination power collection efficiency (PCE) (TCE). was installed at tilt angle 45°, resulting an average PCE 12.42 % TCE 34.7 %. To further understand performance, two-dimensional mathematical model developed validated using data, demonstrating good agreement between simulated actual results. simulation provided valuable insights distribution across different components module, such glass cover, cell, single shell MHP. findings revealed that increasing number MHPs from 12 20 led modest improvement 0.21 2.72 TCE, respectively. Similarly, raising flow rate 0.108 L/s 0.128 resulted corresponding increase 0.25 3.01 These investigations numerical simulations established solid scientific foundation offered practical guidance for implementation MHP-PV/T thereby facilitating efficient utilization future applications.

Abstract Cooling the solar panel with hygroscopic materials offers a potential solution to mitigate its thermal damage and photovoltaic efficiency reduction. However, practical application of this approach is significantly hindered by limited water storage capacity back electrode corrosion. In study, it demonstrated that encapsulating LiCl‐loaded carbon felt in superhydrophobic polytetrafluoroethylene membrane effectively preserves high absorptivity while preventing conventional corrosion issue. This ensures sustainable long‐term passive cooling cells. The high‐salt but corrosion‐resistant (HSCR) material has extremely adsorption capacities, which characterized ability absorb more than 5 times weight within 8 h incubation at 25 °C 90% relative humidity (RH). Under 1 sun illumination, incorporating HSCR reduces temperature 17.8 increasing 10.7%. More importantly, salts encapsulated remain leak‐proof performance can be regenerated after multiple cycles. work provides promising for cooling.
