- 摘要：
- Due to the low efficiency of power generation, a novel photovoltaic (PV) system integrated with phase change material (PCM) and thermoelectric (TE) module was proposed. The system was designed to increase the electricity output by attaching the PCM and TE module to PV cell optimally. To study the annual dynamic performance of the proposed system, a numerical model focusing on solar cell temperature, efficiency and output power was established. The results showed the solar cell temperature of PV-PCM-TE system was decreased from 79.72 degrees C to 57.39 degrees C compared with single PV system, while the PV-TE system was 73.62 degrees C. The annual average efficiency of the PV-PCM-TE system, the PV-TE system and the single PV system were 17.57%, 17.15% and 15.95%, respectively. The all-year electricity generation were 341.97 kWh, 333.87 kWh and 310.47 kWh, respectively. The efficiency of the PV-PCM-TE system was increased by 10.15% and 2.37% than that of the single PV system and PV-TE system respectively. It was confirmed the performance of PV-PCM-TE system was the best. Compared with PV-TE system, the efficiency increased by 3.53% in summer and 0.6% in winter, suggesting that t it was necessary to use PCM and TE module to cool the PV cell in summer.
