Energizing the thermophysical properties of phase change material using carbon-based nano additives for sustainable thermal energy storage application in photovoltaic thermal systems

As solar energy are intermittent in nature and not predictable, researchers and scientists are actively developing efficient thermal energy storage (TES) systems intending to maximize the utilization of solar energy. Phase change materials (PCM) are potential materials that are largely accessed towa...

The newly developed nanocomposite also demonstrated chemically and thermally stable up to a temperature of 210 �C, and the thermal stability was slightly enhanced by adding nanoparticles. This nanocomposite also exhibited improved optical absorptance and reduced transmittance, enhancing its potential for solar energy absorption. It further demonstrated durability, maintaining stability even after undergoing 500 thermal cycles. Notably, the overall efficiency of the nano-enhanced PCM integrated photovoltaic-thermal system (PVT) enhanced by 29 % and 49 % greater than the PVT system and conventional PV system. Given these exceptional characteristics and performance enhancements, this nanocomposite material holds promise for significantly advancing future sustainable TES technologies. ? 2023 Elsevier Ltd Final 2025-03-03T07:44:04Z 2025-03-03T07:44:04Z 2024 Article 10.1016/j.mtsust.2023.100658 2-s2.0-85181174544 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85181174544&doi=10.1016%2fj.mtsust.2023.100658&partnerID=40&md5=a43d0aa400d45fadee8b31add1f15348 https://irepository.uniten.edu.my/handle/123456789/36708 25 100658 Elsevier Ltd Scopus
