Abstract

Solar energy is a renewable energy source that is abundant and emits low emissions. The operating temperature of a solar panel has a significant impact on its efficiency. A 50 Wp polycrystalline solar panel was tested in this experiment using PCM (paraffin) as a passive cooling solution and without it. The PCM was placed on the backplate of the solar panel using a container equipped with fins to enhance cooling efficiency. Simulations were conducted using a solar simulator with varying light intensities of 470 W/m², 650 W/m², 900 W/m², and 1000 W/m², while a blower was used to simulate constant airflow around the surrounding area.Evaluating the panel temperature and calculating the error rate in experimental findings were the goals of the simulation. According to the simulation, the average temperature of a solar panel without cooling reached 59.4°C at an intensity of 1000 W/m2, but the temperature dropped to 57.8°C and 55.4°C, respectively, when PCM cooling with 5 and 10 fins was used.This experiment demonstrated that the application of PCM with a modified container can lower the maximum temperature of the solar panel and increase its maximum efficiency by 1.15% at an intensity of 1000 W/m². This passive cooling system has proven to be effective in reducing the operational temperature of solar panels.

Abstract

The growing demand for clean and efficient energy sources has driven the development of various alternative fuels to replace fossil fuels, which continue to dominate the transportation and industrial sectors. This article presents a comprehensive review of the combustion and emission characteristics of four major types of alternative fuels: bioethanol, biodiesel, biogas, and hydrogen. The review is based on selected scientific literature published between 2020 and 2024, with a focus on thermal efficiency, emission profiles (CO, HC, NOₓ, PM), and relevant emission control technologies. The analysis shows that each fuel exhibits unique characteristics in terms of combustion performance and emission behavior. Hydrogen offers the highest thermal efficiency and zero carbon emissions but requires specialized combustion and storage systems. Bioethanol and biodiesel are relatively compatible with conventional engines, though they face technical limitations and risks of secondary emissions. Biogas demonstrates high potential, particularly when upgraded to biomethane. This study also highlights the importance of integrating fuel selection with appropriate emission control strategies. The findings are expected to serve as a strategic reference for the development of sustainable energy systems in the automotive and industrial sectors

Abstract

The performance of photovoltaic (PV) modules is significantly affected by the increase in operating temperature, which leads to reduced power output and overall efficiency. Therefore, passive cooling strategies are required to maintain stable energy conversion in solar systems. One widely investigated approach is the use of phase change materials (PCM) due to their ability to absorb and release latent heat, although their low thermal conductivity remains a major limitation. This study aims to evaluate the effectiveness of incorporating titanium dioxide nanoparticles into PCM, known as nano-enhanced PCM (NePCM), in improving the cooling performance of PV modules. The experimental method was conducted on a 50 Wp polycrystalline PV module under three conditions: without cooling, with pure PCM, and with titanium dioxide-based NePCM. The preparation of NePCM was carried out using a two-step method involving mechanical stirring and ultrasonic sonication to achieve a homogeneous nanoparticle dispersion. The results demonstrated that the addition of titanium dioxide improved the thermal conductivity of PCM, leading to lower operating temperatures, more stable voltage and power output, and higher energy conversion efficiency compared to both pure PCM and the uncontrolled condition. These findings highlight the potential of titanium dioxide-based NePCM as an effective, economical, and sustainable material for passive cooling applications in photovoltaic systems.
