摘要

This research examines the application of nano-enhanced Phase Change Materials (PCMs) as a method to augment the efficiency of Solar Photovoltaic (SPV) modules via temperature regulation. A comparative assessment was conducted involving three SPV panels: a control panel, a panel that integrates paraffin wax, and a panel that employs Glauber’s salt combined with graphene and aluminum oxide (Al2​O3​) nanoparticles. The nano-enhanced Glauber’s salt panel (Panel-3) recorded the lowest average temperature of 31 °C, which signifies a considerable decrease when juxtaposed with the control (39 °C) and paraffin wax (36 °C) panels. This exemplary thermal management culminated in a peak electrical efficiency of 20% for Panel-3. This outcome signifies a 22% improvement relative to the baseline efficiency of the control panel (17%). The results underscore that this synergistic nano-engineered PCM is remarkably effective in enhancing the efficiency of SPV modules under elevated temperature operational conditions.
