Abstract
Energy generated from photovoltaic (PV) systems is often wasted, with about 80% converted
to heat and only 20% converted to electricity. This indicates the need for further research to
improve the energy conversion efficiency in PV systems. This study aims to analyze the cell
efficiency and power generation in a photovoltaic-thermal (PVT) system with variations in
nano-encapsulated phase change material (NEPCM) concentration and reservoir thickness. The
developed PVT configuration includes a photovoltaic cell layer, a thermal paste layer, a
reservoir wall, and a channel filled with nanofluid containing NEPCM surrounded by a
protective shell. The research method involves simulation using the Finite Element Method to
measure system performance regarding energy conversion efficiency, with encapsulated PCM
concentration variations at 2%, 10%, and 20%. Additionally, the laminar flow velocity used is
0.5 m/s under steady-state conditions, and the thickness of the PCM material used is 1 mm and
15 mm. The results show that increasing the NEPCM concentration by 5% can improve the
electrical and thermal performance of the system by more than 50%. In addition, variations in
reservoir thickness also contribute to the overall efficiency. This study concludes that the
proposed PVT configuration can improve energy efficiency and optimize thermal management
in the system, making it an effective solution for developing renewable energy technologies.
Thus, implementing NEPCM in PVT systems can significantly contribute to overall energy
efficiency.
