This article reports on an innovative PV system integrating phase change material, thermoelectric generator, and thermal collectors to improve module performance. The three technologies help in cooling the solar panel, increasing power generation efficiency by 10.4% compared to standard panels under similar conditions, while also improving temperature control and energy utilization through PCM thickness adjustment and water-cooling plate deployment.
- Integration of technologies: Phase change materials (PCM), thermoelectric generators (TEGs), and thermal collectors are combined to enhance PV module performance.
- Power generation efficiency increase: The integrated system shows a 10.4% higher power output compared to standard panels, thanks to optimized PCM thickness and cooling water use.
- Temperature control: By utilizing TEGs' heat and thermal collectors' capability along with PCM, the system achieves superior temperature regulation.
- Energy recovery: The cooling water helps in capturing and reusing excess heat, thus optimizing energy usage.
- Research publication: Details of this study were published in Solar Energy Magazine's journal article "Experimental and Numerical Study on Photovoltaic Thermoelectric Heat Storage System Based on Phase Change Temperature Control."
